TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with sensors to detect intensity of contacts on touch-sensitive surfaces.

BACKGROUND

The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touchpads and touch-screen displays. Such surfaces are widely used to manipulate user interface objects on a display.

Exemplary manipulations include adjusting the position and/or size of one or more user interface objects or activating buttons or opening files/applications represented by user interface objects, as well as associating metadata with one or more user interface objects or otherwise manipulating user interfaces. Exemplary user interface objects include digital images, video, text, icons, control elements such as buttons and other graphics. A user will, in some circumstances, need to perform such manipulations on user interface objects in a file management program (e.g., Finder from Apple Inc. of Cupertino, Calif.), an image management application (e.g., Aperture, iPhoto, Photos from Apple Inc. of Cupertino, Calif.), a digital content (e.g., videos and music) management application (e.g., iTunes from Apple Inc. of Cupertino, Calif.), a drawing application, a presentation application (e.g., Keynote from Apple Inc. of Cupertino, Calif.), a word processing application (e.g., Pages from Apple Inc. of Cupertino, Calif.), a website creation application (e.g., iWeb from Apple Inc. of Cupertino, Calif.), a disk authoring application (e.g., iDVD from Apple Inc. of Cupertino, Calif.), or a spreadsheet application (e.g., Numbers from Apple Inc. of Cupertino, Calif.).

But existing methods for processing these manipulations are cumbersome and inefficient. In addition, existing methods take longer than necessary, thereby wasting energy. This latter consideration is particularly important in battery-operated devices.

SUMMARY

Accordingly, the present disclosure provides electronic devices with faster, more efficient methods for processing touch inputs. Such methods and interfaces optionally complement or replace conventional methods for processing touch inputs. Such methods and interfaces provide a more efficient human-machine interface by allowing customized processing of touch inputs. Further, such methods reduce the processing power consumed to process touch inputs, conserve power, reduce unnecessary/extraneous/repetitive inputs, and potentially reduce memory usage. For battery-operated devices, such methods and interfaces conserve battery power and increase the time between battery charges.

The above deficiencies and other problems associated with user interfaces for electronic devices with touch-sensitive surfaces are reduced or eliminated by the disclosed devices. In some embodiments, the device is a desktop computer. In some embodiments, the device is portable (e.g., a notebook computer, tablet computer, or handheld device).

It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch-screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch-screen display and/or a touchpad).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick.

The device typically supports a variety of applications, such as one or more of the following: a note taking application, a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices with touch-sensitive displays. FIG. 1A is a block diagram illustrating portable multifunction device 100 with touch-sensitive display system 112 in accordance with some embodiments. Touch-sensitive display system 112 is sometimes called a “touch screen” for convenience, and is sometimes simply called a touch-sensitive display. Device 100 includes memory 102 (which optionally includes one or more non-transitory computer readable storage mediums), memory controller 122, one or more processing units (CPUs) 120, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input or control devices 116, and external port 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more intensity sensors 165 for detecting intensity of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 163 for generating tactile outputs on device 100 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate over one or more communication buses or signal lines 103.

As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 1A are implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing and/or application specific integrated circuits.

Memory 102 optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of device 100, such as CPU(s) 120 and the peripherals interface 118, is, optionally, controlled by memory controller 122.

Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU(s) 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data.

In some embodiments, peripherals interface 118, CPU(s) 120, and memory controller 122 are, optionally, implemented on a single chip, such as chip 104. In some other embodiments, they are, optionally, implemented on separate chips.

Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data is, optionally, retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 106 couples input/output peripherals on device 100, such as touch-sensitive display system 112 and other input or control devices 116, with peripherals interface 118. I/O subsystem 106 optionally includes display controller 156, optical sensor controller 158, intensity sensor controller 159, haptic feedback controller 161, and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input or control devices 116 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 are, optionally, coupled with any (or none) of the following: a keyboard, infrared port, USB port, stylus, and/or a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) optionally include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons optionally include a push button (e.g., 206, FIG. 2).

Touch-sensitive display system 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch-sensitive display system 112. Touch-sensitive display system 112 displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user-interface objects.

Touch-sensitive display system 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic/tactile contact. Touch-sensitive display system 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch-sensitive display system 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch-sensitive display system 112. In some embodiments, a point of contact between touch-sensitive display system 112 and the user corresponds to a finger of the user or a stylus.

Touch-sensitive display system 112 optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch-sensitive display system 112 and display controller 156 optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch-sensitive display system 112. In some embodiments, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch-sensitive display system 112 optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen video resolution is in excess of 400 dpi (e.g., 500 dpi, 800 dpi, or greater). The user optionally makes contact with touch-sensitive display system 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch-sensitive display system 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 optionally also includes one or more optical sensors 164. FIG. 1A shows an optical sensor coupled with optical sensor controller 158 in I/O subsystem 106. Optical sensor(s) 164 optionally include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor(s) 164 receive light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor(s) 164 optionally capture still images and/or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch-sensitive display system 112 on the front of the device, so that the touch screen is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image is obtained (e.g., for selfies, for videoconferencing while the user views the other video conference participants on the touch screen, etc.).

Device 100 optionally also includes one or more tactile output generators 163. FIG. 1A shows a tactile output generator coupled with haptic feedback controller 161 in I/O subsystem 106. Tactile output generator(s) 163 optionally include one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). In some embodiments, tactile output generator(s) 163 receive tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100).

In some embodiments, information is displayed on the touch-screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, position module (or set of instructions) 131, graphics module (or set of instructions) 132, haptic feedback module (or set of instructions) 133, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments, memory 102 stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch-sensitive display system 112; sensor state, including information obtained from the device's various sensors and other input or control devices 116; and location and/or positional information concerning the device's location and/or attitude.

Operating system 126 (e.g., iOS, Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif.

Contact/motion module 130 optionally detects contact with touch-sensitive display system 112 (in conjunction with display controller 156) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes software components for performing various operations related to detection of contact (e.g., by a finger or by a stylus), such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts or stylus contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts and/or stylus contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event. Similarly, tap, swipe, drag, and other gestures are optionally detected for a stylus by detecting a particular contact pattern for the stylus.

Position module 131, in conjunction with accelerometers 167, gyroscopes 168, and/or magnetometers 169, optionally detects positional information concerning the device, such as the device's attitude (roll, pitch, and/or yaw) in a particular frame of reference. Position module 130 includes software components for performing various operations related to detecting the position of the device and detecting changes to the position of the device. In some embodiments, position module 131 uses information received from a stylus being used with the device to detect positional information concerning the stylus, such as detecting the positional state of the stylus relative to the device and detecting changes to the positional state of the stylus.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch-sensitive display system 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Haptic feedback module 133 includes various software components for generating instructions (e.g., instructions used by haptic feedback controller 161) to produce tactile outputs using tactile output generator(s) 163 at one or more locations on device 100 in response to user interactions with device 100.

Text input module 134, which is, optionally, a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

In conjunction with touch-sensitive display system 112, display system controller 156, contact module 130, graphics module 132, audio circuitry 110, speaker 111, RF circuitry 108, and browser module 147, video and music player module 152 includes executable instructions that allow the user to download and play back recorded music and other sound files stored in one or more file formats, such as MP3 or AAC files, and executable instructions to display, present or otherwise play back videos (e.g., on touch-sensitive display system 112, or on an external display connected wirelessly or via external port 124). In some embodiments, device 100 optionally includes the functionality of an MP3 player, such as an iPod (trademark of Apple Inc.).

In conjunction with touch-sensitive display system 112, display controller 156, contact module 130, graphics module 132, and text input module 134, notes module 153 includes executable instructions to create and manage notes, to do lists, and the like in accordance with user instructions.

In conjunction with RF circuitry 108, touch-sensitive display system 112, display system controller 156, contact module 130, graphics module 132, text input module 134, GPS module 135, and browser module 147, map module 154 includes executable instructions to receive, display, modify, and store maps and data associated with maps (e.g., driving directions; data on stores and other points of interest at or near a particular location; and other location-based data) in accordance with user instructions.

In conjunction with touch-sensitive display system 112, display system controller 156, contact module 130, graphics module 132, audio circuitry 110, speaker 111, RF circuitry 108, text input module 134, e-mail client module 140, and browser module 147, online video module 155 includes executable instructions that allow the user to access, browse, receive (e.g., by streaming and/or download), play back (e.g., on touch screen 112, or on an external display connected wirelessly or via external port 124), send an e-mail with a link to a particular online video, and otherwise manage online videos in one or more file formats, such as H.264. In some embodiments, instant messaging module 141, rather than e-mail client module 140, is used to send a link to a particular online video.

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 102 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 102 optionally stores additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 136, 137-155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch-sensitive display system 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display system 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 167, gyroscope(s) 168, magnetometer(s) 169, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display system 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripheral interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views, when touch-sensitive display system 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver module 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 optionally utilizes or calls data updater 176, object updater 177 or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 includes one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

As used herein, a force event refers to a device-generated signal or device-generated data (e.g., a signal or a data object generated or updated by device 100) to indicate status or a change in status of a touch input, such as beginning (e.g., satisfying a minimum force intensity threshold), changing intensity (e.g., increasing or decreasing intensity of the touch input), or changing intensity status (e.g., hard press to exceed an intensity threshold or release the touch input so that the intensity falls below the intensity threshold) of the touch input. Although force events are associated with physical touches (e.g., touches with a finger and/or a stylus) on the touch-sensitive surface, the force events, as described herein, are distinct from the physical touches.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170, and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which optionally include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event 187 include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display system 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display system 112, when a touch is detected on touch-sensitive display system 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module 145. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input-devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 1C is a block diagram illustrating transfer of event object 194 in accordance with some embodiments.

As described above with respect to FIG. 1A, contact/motion module 130 determines status and/or a change in the status of a touch input. In some embodiments, the device generates signal or data (e.g., in the form of a data object) to transfer the determined status and/or the determined change in the status of a touch input to one or more software components. In some embodiments, the data object is called an event object (e.g., event object 194). An event object includes data that represents the status of a corresponding touch input. In some embodiments, event object 194 is a mouse event object (because the touch input is equivalent to an input by a mouse). For example, in such embodiments, a touch input moving across a touch-sensitive surface corresponds to a mouse movement (e.g., a mouse moved event). In some other embodiments, event object 194 is a touch event object that is distinct from a mouse event object. In some embodiments, the touch event object includes data that represents touch-specific properties of a corresponding touch input (e.g., a number of concurrent touches, an orientation of a finger contact or a stylus, etc.). In some embodiments, event object 194 is a force event object that is distinct from a mouse event object (or a touch event object). In some embodiments, the force event object includes data that represents force event specific properties of a corresponding touch input (e.g., an intensity applied by the touch input, a stage/phase of the touch input, etc.). In some embodiments, the event object includes any combination of such properties (e.g., mouse event specific properties, touch event specific properties, and force event specific properties).

In some embodiments, contact/motion module 130 generates (or updates) an event object and sends an event object to one or more applications (e.g., application 136-1, such as e-mail client module 140 in FIG. 1A, and/or application 136-2, such as browser module 147). Alternatively, contact/information module 130 sends information regarding contacts (e.g., raw coordinates of contacts) to one or more applications (e.g., application 1 (136-1) and/or application 2 (136-2)), and an application that receives the information generates (or updates) one or more event objects. In some embodiments, an application includes touch-processing module 220 that generates (or updates) one or more event objects and sends the one or more event objects to a portion of the application other than touch-processing module 220. In some embodiments, touch-processing module 220 is application-independent (e.g., the same touch-processing module is included in each of multiple distinct applications, such as e-mail client application, browser application, etc.). As used herein, that touch-processing module 220 is application-independent means that touch-processing module 220 is not designed specifically for a particular software application. That touch-processing module 220 is application-independent does not mean that touch-processing module 220 is located separate from its associated application. Although touch-processing module 220, in some embodiments, is distinct and separate from its associated application, as shown in FIG. 1C, touch-processing module 220 is included in its associated application in some embodiments. In some embodiments, the application also includes an application core that is specific to the application.

In FIG. 1C, each of application 1 (136-1, such as a e-mail client application) and application 2 (136-2, such as a browser application) includes touch processing module 220. In addition, application 1 (136-1) includes application core 1 (230-1) that is specific to application 1 (136-1) and/or application 2 (136-2) includes application core 2 (230-2) that is specific to application 2 (136-2). For example, application core 1 (230-1) includes instructions for performing operations specific to application 1 (136-1) (e.g., retrieving e-mails from one or more e-mail servers) and application core 2 (230-2) includes instructions for performing operations specific to application 2 (136-2) (e.g., bookmarking a web page).

In some embodiments, event object 194 is sent directly to the destination (e.g., a software component, such as application core 1 (230-1)). Optionally, event object 194 is sent through application programming interface 222. In some embodiments, event object 194 is sent by posting event object 194 (e.g., in queue 218-1) for retrieval by application core 1 (230-1).

In some embodiments, event object 194 includes force information. In some embodiments, a mouse event object includes force information (e.g., raw or normalized force applied by the touch input). In some embodiments, a touch event object includes force information. In some embodiments, a force event object includes force information.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen (e.g., touch-sensitive display system 112, FIG. 1A) in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In these embodiments, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 optionally also includes one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 is, optionally, used to navigate to any application 136 in a set of applications that are, optionally executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on the touch-screen display.

In some embodiments, device 100 includes the touch-screen display, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, Subscriber Identity Module (SIM) card slot 210, head set jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In some embodiments, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensity of contacts on touch-sensitive display system 112 and/or one or more tactile output generators 163 for generating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPU's) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch-screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 163 described above with reference to FIG. 1A), sensors 359 (e.g., touch-sensitive, optical, contact intensity, proximity, acceleration, attitude, and/or magnetic sensors similar to sensors 112, 164, 165, 166, 167, 168, and 169 described above with reference to FIG. 1A).

Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1A) optionally does not store these modules.

Each of the above identified elements in FIG. 3 is, optionally, stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 370 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 370 optionally stores additional modules and data structures not described above.

FIG. 4 is a block diagram of an exemplary electronic stylus 203 in accordance with some embodiments. Electronic stylus 203 is sometimes simply called a stylus. Stylus 203 includes memory 402 (which optionally includes one or more computer readable storage mediums), memory controller 422, one or more processing units (CPUs) 420, peripherals interface 418, RF circuitry 408, input/output (I/O) subsystem 406, and other input or control devices 416. Stylus 203 optionally includes external port 424 and one or more optical sensors 464. Stylus 203 optionally includes one or more intensity sensors 465 for detecting intensity of contacts of stylus 203 on device 100 (e.g., when stylus 203 is used with a touch-sensitive surface such as touch-sensitive display system 112 of device 100) or on other surfaces (e.g., a desk surface). Stylus 203 optionally includes one or more tactile output generators 463 for generating tactile outputs on stylus 203. These components optionally communicate over one or more communication buses or signal lines 403.

In some embodiments, the term “tactile output,” discussed above, refers to physical displacement of an accessory (e.g., stylus 203) of a device (e.g., device 100) relative to a previous position of the accessory, physical displacement of a component of an accessory relative to another component of the accessory, or displacement of the component relative to a center of mass of the accessory that will be detected by a user with the user's sense of touch. For example, in situations where the accessory or the component of the accessory is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the accessory or the component of the accessory. For example, movement of a component (e.g., the housing of stylus 203) is, optionally, interpreted by the user as a “click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as a “click” even when there is no movement of a physical actuator button associated with the stylus that is physically pressed (e.g., displaced) by the user's movements. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., a “click,”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that stylus 203 is only one example of an electronic stylus, and that stylus 203 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 4 are implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing and/or application specific integrated circuits.

Memory 402 optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more flash memory devices, or other non-volatile solid-state memory devices. Access to memory 402 by other components of stylus 203, such as CPU(s) 420 and the peripherals interface 418, is, optionally, controlled by memory controller 422.

Peripherals interface 418 can be used to couple input and output peripherals of the stylus to CPU(s) 420 and memory 402. The one or more processors 420 run or execute various software programs and/or sets of instructions stored in memory 402 to perform various functions for stylus 203 and to process data.

In some embodiments, peripherals interface 418, CPU(s) 420, and memory controller 422 are, optionally, implemented on a single chip, such as chip 404. In some other embodiments, they are, optionally, implemented on separate chips.

RF (radio frequency) circuitry 408 receives and sends RF signals, also called electromagnetic signals. RF circuitry 408 converts electrical signals to/from electromagnetic signals and communicates with device 100 or 300, communications networks, and/or other communications devices via the electromagnetic signals. RF circuitry 408 optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth.

I/O subsystem 406 couples input/output peripherals on stylus 203, such as other input or control devices 416, with peripherals interface 418. I/O subsystem 406 optionally includes optical sensor controller 458, intensity sensor controller 459, haptic feedback controller 461, and one or more input controllers 460 for other input or control devices. The one or more input controllers 460 receive/send electrical signals from/to other input or control devices 416. The other input or control devices 416 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, click wheels, and so forth. In some alternate embodiments, input controller(s) 460 are, optionally, coupled with any (or none) of the following: an infrared port and/or a USB port.

Stylus 203 also includes power system 462 for powering the various components.

Stylus 203 optionally also includes one or more optical sensors 464. FIG. 4 shows an optical sensor coupled with optical sensor controller 458 in I/O subsystem 406. Optical sensor(s) 464 optionally include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor(s) 464 receive light from the environment, projected through one or more lens, and converts the light to data representing an image.

Stylus 203 optionally also includes one or more contact intensity sensors 465. FIG. 4 shows a contact intensity sensor coupled with intensity sensor controller 459 in I/O subsystem 406. Contact intensity sensor(s) 465 optionally include one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a surface). Contact intensity sensor(s) 465 receive contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a tip of stylus 203.

Stylus 203 optionally also includes one or more proximity sensors 466. FIG. 4 shows proximity sensor 466 coupled with peripherals interface 418. Alternately, proximity sensor 466 is coupled with input controller 460 in I/O subsystem 406. In some embodiments, the proximity sensor determines proximity of stylus 203 to an electronic device (e.g., device 100).

Stylus 203 optionally also includes one or more tactile output generators 463. FIG. 4 shows a tactile output generator coupled with haptic feedback controller 461 in I/O subsystem 406. Tactile output generator(s) 463 optionally include one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Tactile output generator(s) 463 receive tactile feedback generation instructions from haptic feedback module 433 and generates tactile outputs on stylus 203 that are capable of being sensed by a user of stylus 203. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a length (e.g., a body or a housing) of stylus 203 and, optionally, generates a tactile output by moving stylus 203 vertically (e.g., in a direction parallel to the length of stylus 203) or laterally (e.g., in a direction normal to the length of stylus 203).

Stylus 203 optionally also includes one or more accelerometers 467, gyroscopes 468, and/or magnetometers 470 (e.g., as part of an inertial measurement unit (IMU)) for obtaining information concerning the location and positional state of stylus 203. FIG. 4 shows sensors 467, 469, and 470 coupled with peripherals interface 418. Alternately, sensors 467, 469, and 470 are, optionally, coupled with an input controller 460 in I/O subsystem 406. Stylus 203 optionally includes a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location of stylus 203.

In some embodiments, the software components stored in memory 402 include operating system 426, communication module (or set of instructions) 428, contact/motion module (or set of instructions) 430, position module (or set of instructions) 431, and Global Positioning System (GPS) module (or set of instructions) 435. Furthermore, in some embodiments, memory 402 stores device/global internal state 457, as shown in FIG. 4. Device/global internal state 457 includes one or more of: sensor state, including information obtained from the stylus's various sensors and other input or control devices 416; positional state, including information regarding the stylus's position (e.g., position, orientation, tilt, roll and/or distance, as shown in FIGS. 5A and 5B) relative to a device (e.g., device 100); and location information concerning the stylus's location (e.g., determined by GPS module 435).

Operating system 426 (e.g., iOS, Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 428 optionally facilitates communication with other devices over one or more external ports 424 and also includes various software components for handling data received by RF circuitry 408 and/or external port 424. External port 424 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif.

Contact/motion module 430 optionally detects contact with stylus 203 and other touch-sensitive devices of stylus 203 (e.g., buttons or other touch-sensitive components of stylus 203). Contact/motion module 430 includes software components for performing various operations related to detection of contact (e.g., detection of a tip of the stylus with a touch-sensitive display, such as touch screen 112 of device 100, or with another surface, such as a desk surface), such as determining if contact has occurred (e.g., detecting a touch-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement (e.g., across touch screen 112 of device 100), and determining if the contact has ceased (e.g., detecting a lift-off event or a break in contact). In some embodiments, contact/motion module 430 receives contact data from I/O subsystem 406. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. As noted above, in some embodiments, one or more of these operations related to detection of contact are performed by the device using contact/motion module 130 (in addition to or in place of the stylus using contact/motion module 430).

Contact/motion module 430 optionally detects a gesture input by stylus 203. Different gestures with stylus 203 have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a single tap gesture includes detecting a touch-down event followed by detecting a lift-off event at the same position (or substantially the same position) as the touch-down event (e.g., at the position of an icon). As another example, detecting a swipe gesture includes detecting a touch-down event followed by detecting one or more stylus-dragging events, and subsequently followed by detecting a lift-off event. As noted above, in some embodiments, gesture detection is performed by the device using contact/motion module 130 (in addition to or in place of the stylus using contact/motion module 430).

Position module 431, in conjunction with accelerometers 467, gyroscopes 468, and/or magnetometers 469, optionally detects positional information concerning the stylus, such as the stylus's attitude (roll, pitch, and/or yaw) in a particular frame of reference. Position module 431, in conjunction with accelerometers 467, gyroscopes 468, and/or magnetometers 469, optionally detects stylus movement gestures, such as flicks, taps, and rolls of the stylus. Position module 431 includes software components for performing various operations related to detecting the position of the stylus and detecting changes to the position of the stylus in a particular frame of reference. In some embodiments, position module 431 detects the positional state of the stylus relative to the device and detects changes to the positional state of the stylus relative to the device. As noted above, in some embodiments, device 100 or 300 determines the positional state of the stylus relative to the device and changes to the positional state of the stylus using position module 131 (in addition to or in place of the stylus using position module 431).

Haptic feedback module 433 includes various software components for generating instructions used by tactile output generator(s) 463 to produce tactile outputs at one or more locations on stylus 203 in response to user interactions with stylus 203.

GPS module 435 determines the location of the stylus and provides this information for use in various applications (e.g., to applications that provide location-based services such as an application to find missing devices and/or accessories).

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 402 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 402 optionally stores additional modules and data structures not described above.

FIGS. 5A-5B illustrate a positional state of stylus 203 relative to a touch-sensitive surface (e.g., touch screen 112 of device 100) in accordance with some embodiments. In some embodiments, the positional state of stylus 203 corresponds to (or indicates): a position of a projection of a tip (or other representative portion) of the stylus on the touch-sensitive surface (e.g., (x,y) position 504, FIG. 5A), an orientation of the stylus relative to the touch-sensitive surface (e.g., orientation 506, FIG. 5A), a tilt of the stylus relative to the touch-sensitive surface (e.g., tilt 512, FIG. 5B), and/or a distance of the stylus relative to the touch-sensitive surface (e.g., distance 514, FIG. 5B). In some embodiments, the positional state of stylus 203 corresponds to (or indicates) a pitch, yaw, and/or roll of the stylus (e.g., an attitude of the stylus relative to a particular frame of reference, such as a touch-sensitive surface (e.g., touch screen 112) or the ground). In some embodiments, the positional state includes a set of positional parameters (e.g., one or more positional parameters). In some embodiments, the positional state is detected in accordance with one or more measurements from stylus 203 that are sent to an electronic device (e.g., device 100). For example, the stylus measures the tilt (e.g., tilt 512, FIG. 5B) and/or the orientation (e.g., orientation 506, FIG. 5A) of the stylus and sends the measurement to device 100. In some embodiments, the positional state is detected in accordance with raw output, from one or more electrodes in the stylus, that is sensed by a touch-sensitive surface (e.g., touch screen 112 of device 100) instead of, or in combination with positional state detected in accordance with one or more measurements from stylus 203. For example, the touch-sensitive surface receives raw output from one or more electrodes in the stylus and calculates the tilt and/or the orientation of the stylus based on the raw output (optionally, in conjunction with positional state information provided by the stylus based on sensor measurements generated by the stylus).

FIG. 5A illustrates stylus 203 relative to a touch-sensitive surface (e.g., touch screen 112 of device 100) from a viewpoint directly above the touch-sensitive surface, in accordance with some embodiments. In FIG. 5A, z axis 594 points out of the page (i.e., in a direction normal to a plane of touch screen 112), x axis 590 is parallel to a first edge (e.g., a length) of touch screen 112, y axis 592 is parallel to a second edge (e.g., a width) of touch screen 112, and y axis 592 is perpendicular to x axis 590.

FIG. 5A illustrates the tip of stylus 203 at (x,y) position 504. In some embodiments, the tip of stylus 203 is a terminus of the stylus configured for determining proximity of the stylus to a touch-sensitive surface (e.g., touch screen 112). In some embodiments, the projection of the tip of the stylus on the touch-sensitive surface is an orthogonal projection. In other words, the projection of the tip of the stylus on the touch-sensitive surface is a point at the end of a line from the stylus tip to the touch-sensitive surface that is normal to a surface of the touch-sensitive surface (e.g., (x,y) position 504 at which the tip of the stylus would touch the touch-sensitive surface if the stylus were moved directly along a path normal to the touch-sensitive surface). In some embodiments, the (x,y) position at the lower left corner of touch screen 112 is position (0,0) (e.g., (0,0) position 502) and other (x,y) positions on touch screen 112 are relative to the lower left corner of touch screen 112. Alternatively, in some embodiments, the (0,0) position is located at another position of touch screen 112 (e.g., in the center of touch screen 112) and other (x,y) positions are relative to the (0,0) position of touch screen 112.

Further, FIG. 5A illustrates stylus 203 with orientation 506. In some embodiments, orientation 506 is an orientation of a projection of stylus 203 onto touch screen 112 (e.g., an orthogonal projection of a length of stylus 203 or a line corresponding to the line between the projection of two different points of stylus 203 onto touch screen 112). In some embodiments, orientation 506 is relative to at least one axis in a plane parallel to touch screen 112. In some embodiments, orientation 506 is relative to a single axis in a plane parallel to touch screen 112 (e.g., axis 508, with a clockwise rotation angle from axis 508 ranging from 0 degrees to 360 degrees, as shown in FIG. 5A). Alternatively, in some embodiments, orientation 506 is relative to a pair of axes in a plane parallel to touch screen 112 (e.g., x axis 590 and y axis 592, as shown in FIG. 5A, or a pair of axes associated with an application displayed on touch screen 112).

In some embodiments, an indication (e.g., indication 516) is displayed on a touch-sensitive display (e.g., touch screen 112 of device 100). In some embodiments, indication 516 shows where the stylus will touch (or mark) the touch-sensitive display before the stylus touches the touch-sensitive display. In some embodiments, indication 516 is a portion of a mark that is being drawn on the touch-sensitive display. In some embodiments, indication 516 is separate from a mark that is being drawn on the touch-sensitive display and corresponds to a virtual “pen tip” or other element that indicates where a mark will be drawn on the touch-sensitive display.

In some embodiments, indication 516 is displayed in accordance with the positional state of stylus 203. For example, in some circumstances, indication 516 is displaced from (x,y) position 504 (as shown in FIGS. 5A and 5B), and in other circumstances, indication 516 is not displaced from (x,y) position 504 (e.g., indication 516 is displayed at or near (x,y) position 504 when tilt 512 is zero degrees). In some embodiments, indication 516 is displayed, in accordance with the positional state of the stylus, with varying color, size (or radius or area), opacity, and/or other characteristics. In some embodiments, the displayed indication accounts for thickness of a glass layer on the touch-sensitive display, so as to carry through the indication “onto the pixels” of the touch-sensitive display, rather than displaying the indication “on the glass” that covers the pixels.

FIG. 5B illustrates stylus 203 relative to a touch-sensitive surface (e.g., touch screen 112 of device 100) from a side viewpoint of the touch-sensitive surface, in accordance with some embodiments. In FIG. 5B, z axis 594 points in a direction normal to the plane of touch screen 112, x axis 590 is parallel to a first edge (e.g., a length) of touch screen 112, y axis 592 is parallel to a second edge (e.g., a width) of touch screen 112, and y axis 592 is perpendicular to x axis 590.

FIG. 5B illustrates stylus 203 with tilt 512. In some embodiments, tilt 512 is an angle relative to a normal (e.g., normal 510) to a surface of the touch-sensitive surface (also called simply the normal to the touch-sensitive surface). As shown in FIG. 5B, tilt 512 is zero when the stylus is perpendicular/normal to the touch-sensitive surface (e.g., when stylus 203 is parallel to normal 510) and the tilt increases as the stylus is tilted closer to being parallel to the touch-sensitive surface.

Further, FIG. 5B illustrates distance 514 of stylus 203 relative to the touch-sensitive surface. In some embodiments, distance 514 is the distance from the tip of stylus 203 to the touch-sensitive surface, in a direction normal to the touch-sensitive surface. For example, in FIG. 5B, distance 514 is the distance from the tip of stylus 203 to (x,y) position 504.

Although the terms, “x axis,” “y axis,” and “z axis,” are used herein to illustrate certain directions in particular figures, it will be understood that these terms do not refer to absolute directions. In other words, an “x axis” could be any respective axis, and a “y axis” could be a particular axis that is distinct from the x axis. Typically, the x axis is perpendicular to the y axis. Similarly, a “z axis” is distinct from the “x axis” and the “y axis,” and is typically perpendicular to both the “x axis” and the “y axis.”

Further, FIG. 5B illustrates roll 518, a rotation about the length (long axis) of stylus 203.

Attention is now directed towards embodiments of user interfaces (‘UI’) that are, optionally, implemented on portable multifunction device 100.

FIG. 6A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device 300. In some embodiments, user interface 600 includes the following elements, or a subset or superset thereof:

It should be noted that the icon labels illustrated in FIG. 6A are merely exemplary. For example, in some embodiments, icon 622 for video and music player module 152 is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

FIG. 6B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 651 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from display 650. Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 359) for detecting intensity of contacts on touch-sensitive surface 651 and/or one or more tactile output generators 359 for generating tactile outputs for a user of device 300.

FIG. 6B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 651 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from display 650. Many of the examples that follow will be given with reference to a device that detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 6B. In some embodiments, the touch-sensitive surface (e.g., 651 in FIG. 6B) has a primary axis (e.g., 652 in FIG. 6B) that corresponds to a primary axis (e.g., 653 in FIG. 6B) on the display (e.g., 650). In accordance with these embodiments, the device detects contacts (e.g., 660 and 662 in FIG. 6B) with touch-sensitive surface 651 at locations that correspond to respective locations on the display (e.g., in FIG. 6B, 660 corresponds to 668 and 662 corresponds to 670). In this way, user inputs (e.g., contacts 660 and 662, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 651 in FIG. 6B) are used by the device to manipulate the user interface on the display (e.g., 650 in FIG. 6B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures, etc.), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a stylus input).

As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector,” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 651 in FIG. 6B) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch-screen display (e.g., touch-sensitive display system 112 in FIG. 1A or the touch screen in FIG. 6A) that enables direct interaction with user interface elements on the touch-screen display, a detected contact on the touch-screen acts as a “focus selector,” so that when an input (e.g., a press input by the contact) is detected on the touch-screen display at a location of a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch-screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch-screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact or a stylus contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average or a sum) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be readily accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button).

In some embodiments, contact/motion module 130 and/or 430 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse “click” threshold of a trackpad or touch-screen display can be set to any of a large range of predefined thresholds values without changing the trackpad or touch-screen display hardware. Additionally, in some embodiments, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds may include a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first intensity threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second intensity threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more intensity thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective option or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation.

In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location (e.g., a drag gesture), at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location may be based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm may be applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity.

The user interface figures (e.g., FIGS. 7A-7BBB) described below optionally include various intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to one or more intensity thresholds (e.g., a first intensity threshold I_(L), a second intensity threshold I_(M), a third intensity threshold I_(H), and/or one or more other intensity thresholds). This intensity diagram is typically not part of the displayed user interface, but is provided to aid in the interpretation of the figures. In some embodiments, the first intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the second and third intensity thresholds correspond to intensities at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the first intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

In some embodiments, the response of the device to inputs detected by the device depends on criteria based on the contact intensity during the input. For example, for some inputs, the intensity of a contact exceeding a first intensity threshold during the input triggers a first response. In some embodiments, the response of the device to inputs detected by the device depends on criteria that include both the contact intensity during the input and time-based criteria. For example, for some inputs, the intensity of a contact exceeding a second intensity threshold during the input, greater than the first intensity threshold (e.g., for a light press), triggers a second response only if a delay time has elapsed between meeting the first intensity threshold and meeting the second intensity threshold. This delay time is typically less than 200 ms in duration (e.g., 40, 100, or 120 ms, depending on the magnitude of the second intensity threshold, with the delay time increasing as the second intensity threshold increases). This delay time helps to avoid accidental triggering of the second response. As another example, for some inputs, there is a reduced-sensitivity time period that occurs after the time at which the first intensity threshold is met. During the reduced-sensitivity time period, the second intensity threshold is increased. This temporary increase in the second intensity threshold also helps to avoid accidental triggering of the second response. For other inputs, the second response does not depend on time-based criteria.

In some embodiments, one or more of the input intensity thresholds and/or the corresponding outputs vary based on one or more factors, such as user settings, contact motion, input timing, application running, rate at which the intensity is applied, number of concurrent inputs, user history, environmental factors (e.g., ambient noise), focus selector position, and the like. Exemplary factors are described in U.S. patent application Ser. Nos. 14/399,606 and 14/624,296, which are incorporated by reference herein in their entireties.

An increase of characteristic intensity of the contact from an intensity below the intensity threshold I_(L) to an intensity between the intensity threshold I_(L) and the intensity threshold I_(M) is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the intensity threshold I_(M) to an intensity above the intensity threshold I_(M) is sometimes referred to as a “deep press” input. In some embodiments, an increase of characteristic intensity of the contact from an intensity below the intensity threshold I_(H) to an intensity above the intensity threshold I_(H) is also called a “deep press” input. An increase of characteristic intensity of the contact from an intensity below a contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the intensity threshold I_(L) is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero. In some illustrations a shaded circle or oval is used to represent intensity of a contact on the touch-sensitive surface. In some illustrations, a circle or oval without shading is used represent a respective contact on the touch-sensitive surface without specifying the intensity of the respective contact.

In some embodiments, described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., the respective operation is performed on a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., the respective operation is performed on an “up stroke” of the respective press input).

In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., the respective operation is performed on an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

For ease of explanation, the description of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. As described above, in some embodiments, the triggering of these responses also depends on time-based criteria being met (e.g., a delay time has elapsed between a low intensity threshold being met and a high intensity threshold being met).

User Interfaces and Associated Processes

Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device, such as portable multifunction device 100 or device 300, with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface.

FIGS. 7A-7BBB illustrate exemplary user interfaces for processing touch inputs with instructions in a web page in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 8A-8C and FIG. 9. Although some of the examples which follow will be given with reference to inputs on a touch-sensitive surface 651 that is separate from display 650, in some embodiments, the device detects inputs on a touch-screen display (where the touch-sensitive surface and the display are combined), as shown in FIG. 6A.

FIG. 7A illustrates that user interface 706 on display 650 includes a user interface of a mail application (e.g., e-mail client module 140, FIG. 1A).

FIG. 7A also illustrates state machines 704 for gesture recognizers. State machines 704 for gesture recognizers as well as event handling operations (including handling of gesture events) are described in detail in Appendix A, which is incorporated by reference herein in its entirety. In this example, state machines 704 for four gesture recognizers are shown, each represented in FIG. 7A by a single letter: a reveal gesture recognizer (R), a preview gesture recognizer (P), a tap gesture recognizer (T) and a commit gesture recognizer (C). As shown in FIG. 7A, distinct intensity thresholds, are associated with three of these gesture recognizers: a first intensity threshold I_(L) is associated with the reveal gesture recognizer, a second intensity threshold I_(M) is associated with the preview gesture recognizer, and a third intensity threshold I_(H) is associated with the commit gesture recognizer. In this example, the third intensity threshold I_(H) is greater than (i.e., higher than) the second intensity threshold I_(M), and the second intensity threshold I_(M) is greater than (i.e., higher than) the first intensity threshold I_(L).

FIG. 7A shows the position of a focus selector 705 positioned over a user interface object 708 or feature in user interface 706. The position of the focus selector 705 corresponds to the position of a corresponding user input on a touch-sensitive surface (e.g., touch sensitive surface 651 or a touch-sensitive surface of a touch-screen display 650, FIG. 6B).

As shown in user input intensity graph 702, the intensity (also called contract intensity) of the user input is initially below the first intensity threshold I_(L).

FIG. 7B shows a new user interface 710 that results when the user input corresponding to focus selector 705 is a tap gesture. Intensity profiles 7102, 7104, 7106 and 7108 all correspond to tap gestures than end prior to completion of a first predefined time period, represented by the time period ending at time 7002. All four of these intensity profiles correspond to tap gestures, even when the peak intensity of the gesture is greater than one or more of the three intensity thresholds, because the user input does not remain on the touch sensitive surface for a first predefined time period.

In some embodiments, intensity profile 7110 also corresponds to a tap gesture, even though the user input remains on the touch sensitive surface for the first predefined time period, because the user input never exceeds the first intensity threshold I_(L). However, in some other embodiments, a user input having intensity profile 7110 is construed as a non-event that does not cause performance of any operation.

FIG. 7B also shows that the state machine for the tap gesture recognizer (T) transitions from the Possible state, as shown in FIG. 7A, to the Recognized state. Furthermore, FIG. 7B shows that the state machines for the reveal gesture recognizer (R), preview gesture recognizer (P), and commit gesture recognizer (C) have all transitioned from the Possible state to the Failed state. This is because, for every one of intensity profiles 7102, 7104, 7106, 7108 and 7110, the input has failed to satisfy either an intensity input criteria or a duration criteria required for gesture recognition by those gesture recognizers. Alternatively, or in addition, each of the gesture recognizers that transition to the Failed state do so because recognition of a tap gesture by the tap gesture recognizer (T) causes all the other gesture recognizers to transition to the Failed state.

FIG. 7C shows a transition of user interface 706 from the state of that user interface in FIG. 7A. In particular, in accordance with a determination that the intensity of the user input satisfies intensity input criteria for the reveal gesture recognizer (R), the reveal gesture recognizer transitions to the Began state. In some embodiments, the intensity of the user input satisfies intensity input criteria for the reveal gesture recognizer (R) when the intensity of the user input reaches the first intensity threshold I_(L). In some other embodiments, the intensity of the user input satisfies intensity input criteria for the reveal gesture recognizer (R) when the intensity of the user input exceeds the first intensity threshold I_(L).

Optionally, when the reveal gesture recognizer transitions to the Began state, focus selector 705 is displayed, or provided for display, with a different appearance than when the reveal gesture recognizer is in the Possible state.

In some embodiments, in accordance with a determination that the intensity of the user input satisfies intensity input criteria for the reveal gesture recognizer (R), an internal event 7004 is generated, indicating that the intensity of the user input satisfies intensity input criteria for the reveal gesture recognizer (R). That event is provided to the reveal gesture recognizer (R), which transitions to the Began state in response to the event. Event 7004 optionally includes a progress indicator, graphically represented in FIG. 7C by progress indicator 750, which indicates an amount of progress of the intensity of the user input between first intensity threshold I_(L) and a second intensity threshold I_(M). In some embodiments, the progress indicator 750 is a normalized value, for example having a value between 0 and 1, and initially have a value of 0, or a value close to zero, when the intensity of the user input equals or has reached the first intensity threshold I_(L).

In FIG. 7D, the intensity of the user input has changed from an intensity equal or approximately equal to the first intensity threshold I_(L), as shown in FIG. 7C, to an intensity above the first intensity threshold I_(L) and below the second intensity threshold I_(M). In response to this increase in intensity of the user input, the value of progress indicator 750 increases to a value indicating where in the range between the first intensity threshold I_(L) and the second intensity threshold I_(M) the current user input intensity falls. Furthermore, the state of the reveal gesture recognizer (R) transitions to the Changed state, and user interface 706 is blurred, or transitions to a blur state, excluding the user interface object 708, corresponding to the position of the user input, which is not blurred. In this way, the user is notified that an action or operation with respect to user interface object 708 will occur if the user continues to increase the intensity of the user input.

In FIG. 7E, the intensity of the user input has further increased from the intensity of the user input in FIG. 7D. The reveal gesture recognizer (R) remains in the Changed state. Further, a small version of a preview area 712, sometimes called the preview platter, is displayed in or over user interface 706, which remains blurred except for object 708. In some embodiments, the size of the preview area 712 corresponds to a value of progress indicator 750. In some embodiments, preview area 712 is initially displayed only when the progress indicator 750 reaches a predefined value, such as 0.4 or 0.5.

In FIG. 7F, the intensity of the user input has further increased from the intensity of the user input in FIG. 7E. The reveal gesture recognizer (R) remains in the Changed state, and user interface 706 remains blurred except for object 708. Further, the size of preview area 712, as displayed in or over user interface 706, has increased in accordance with the increased intensity of the user input, or in accordance with the increased value of progress indicator 750. In FIG. 7F, the preview area 712 has increase in size sufficiently to enable a user to read the contents of the preview area 712. In this example, preview area 712 includes a preview of information corresponding to the user interface object 708 over which the focus selector 705 is positioned. In this example, the previewed information is a list of connections associated with the person corresponding to the user interface object 708 over which the focus selector 705 is positioned.

In FIG. 7G, the intensity of the user input has further increased from the intensity of the user input in FIG. 7E to an intensity equal or approximately equal to the second intensity threshold I_(M). Progress indicator 750 now has its maximum value, for example 1, indicating that the intensity of the user input has reached to maximum value of the range corresponding to that progress indicator. Optionally, a second progress indicator 752 is generated, indicating a status of the user input with respect to the intensity range between the second intensity threshold I_(M) and the third intensity threshold I_(H). In FIG. 7G, second progress indicator 752 has its minimum value, indicating that the intensity of the user input is at the low end of the intensity range between the second intensity threshold I_(M) and the third intensity threshold I_(H).

In accordance with the intensity of the user input reaching the second intensity threshold I_(M), the reveal gesture recognizer (R) remains in the Changed state, or alternatively transitions to the Canceled state, the tap gesture recognizer transitions to the Failed state, the preview gesture recognizer transitions to the Began state, and preview area 712 is displayed at either its maximum size (sometimes herein called full size), or at a size close to its maximum size. Preview area 712 continues to include a preview of information corresponding to the user interface object 708 over which the focus selector 705 is positioned.

In FIG. 7H, the intensity of the user input has further increased from the intensity of the user input in FIG. 7G to an intensity above the second intensity threshold I_(M) and below the third intensity threshold I_(H). Progress indicator 750 remains its maximum value, for example 1, since the intensity of the user input is above the maximum value of the range corresponding to that progress indicator. Second progress indicator 752 now has an intermediate value, between the minimum and maximum values for that progress indicator 752, indicating the current status of the user input with respect to the intensity range between the second intensity threshold I_(M) and the third intensity threshold I_(H).

In accordance with the intensity of the user input exceeding the second intensity threshold I_(M), the reveal gesture recognizer (R) remains in the Changed state, or alternatively transitions to the Canceled state, the tap gesture recognizer remains in the Failed state, the preview gesture recognizer transitions to the Changed state, and preview area 712 is displayed at its maximum size (sometimes herein called full size). Preview area 712 continues to include a preview of information corresponding to the user interface object 708 over which the focus selector 705 is positioned.

In FIG. 7I, the intensity of the user input has further increased from the intensity of the user input in FIG. 7H to an intensity at or above the third intensity threshold I_(H). Progress indicator 750 remains its maximum value, for example 1, since the intensity of the user input is above the maximum value of the range corresponding to that progress indicator. Second progress indicator 752 now has its maximum value, indicating the current status of the user input with respect to the intensity range between the second intensity threshold I_(M) and the third intensity threshold I_(H). Optionally, upon reaching the third intensity threshold I_(H), an event 7008 is generated indicating the intensity of the user input and optionally including one or both progress indicators 750, 752.

In accordance with the intensity of the user input reaching the third intensity threshold I_(H), the reveal gesture recognizer (R) transitions to the Canceled state, the tap gesture recognizer remains in the Failed state, the preview gesture recognizer transitions to the Canceled state, and the commit gesture recognizer transitions to the Recognized state. Furthermore, in accordance with the intensity of the user input reaching the third intensity threshold I_(H), preview area 712 is no longer displayed, and instead a new user interface 710 corresponding to selection of user interface object 708 is displayed. In the example shown in FIG. 7I, selection of user interface object 708 has caused connection information for person or entity corresponding to user interface object 708 be displayed, or provided for display.

In FIG. 7J, the intensity of the user input has decreased from the intensity of the user input in FIG. 7H to an intensity below the second intensity threshold I_(M). In this example, the intensity of the user input has not reached the third intensity threshold I_(H) and therefore the commit gesture recognizer remains in the Possible state. Furthermore, progress indicator 750 transitions to a value below its maximum value, since the intensity of the user input is now below the maximum value of the range corresponding to that progress indicator. Second progress indicator 752 now has its minimum value, indicating the current status of the user input with respect to the intensity range between the second intensity threshold I_(M) and the third intensity threshold I_(H). In other words, since the intensity of the user input is below the second intensity threshold I_(M), second progress indicator 752 has its minimum value. Optionally, the change in intensity of the user input causes an event (not shown) to be generated, where the event includes information indicating the intensity of the user input and optionally including one or both progress indicators 750, 752.

In accordance with the intensity of the user input decreasing to an intensity below the second intensity threshold I_(M), without first reaching the third intensity threshold I_(H), the reveal gesture recognizer (R) remains in the Changed state, the tap gesture recognizer remains in the Failed state, the preview gesture recognizer remains in the Changed state, and the commit gesture recognizer remains in the Possible state. Furthermore, in accordance with the decreased intensity of the user input, the size of preview area 712 decreases from the size at which it was displayed when the intensity of the user input was higher (see FIG. 7H).

In FIG. 7K, the user input ceases, as indicated by a zero intensity of the user input, after previously reaching or exceeding the first intensity threshold I_(L) (corresponding to intensity profile 7112) or the second intensity threshold I_(M) (corresponding to intensity profile 7114), without exceeding the third intensity threshold I_(H). Furthermore, the duration of the gesture exceeds the first predefined period corresponding to time 7002, indicating that the gesture does not meet tap criteria, which includes that the input ceases to remain on the touch-sensitive surface during the first predefined time period. As a result, the tap gesture recognizer transitions to the Failed state, and the commit gesture recognizer also transitions to the Failed State.

In accordance with intensity profile 7114 in FIG. 7K, the preview gesture recognizer transitions to the Recognized state during the gesture in response to the intensity of the input satisfying intensity input criteria, including that the input satisfies the second intensity threshold I_(M), and the input remaining on the touch-sensitive surface for the first predefined time period, and subsequently transitions to the Failed state in response to the input ceasing to remain on the touch-sensitive surface.

In accordance with intensity profile 7112 in FIG. 7K, the preview gesture recognizer transitions from the Possible state to the Failed state, without first transitioning to the Recognized state, since the intensity input criteria for preview gesture recognizer are not satisfied, even temporarily, by an input with intensity profile 7112.

Optionally, the reveal gesture recognizer transitions to the Recognized state in response to an input with either intensity profile 7112 or intensity profile 7114, since the intensity of the input exceeds the first intensity threshold I_(L) and the input remains on the touch-sensitive surface for the first predefined time period. In some embodiments, not shown in FIG. 7K, the reveal gesture recognizer transitions to the Canceled state in response to the input ceasing to remain on the touch-sensitive surface.

In FIG. 7L, the set of active gesture recognizers includes a reveal gesture recognizer (R), a preview gesture recognizer (P), a pan or scroll gesture recognizer (S) and a commit gesture recognizer (C). As shown in FIG. 7L, distinct intensity thresholds, are associated with three of these gesture recognizers: a first intensity threshold I_(L) is associated with the reveal gesture recognizer, a second intensity threshold I_(M) is associated with the preview gesture recognizer, and a third intensity threshold I_(H) is associated with the commit gesture recognizer.

FIG. 7L shows the position of a focus selector 707 positioned over a user interface object 708 or feature in user interface 706. The position of the focus selector 705 corresponds to the position of a corresponding user input on a touch-sensitive surface (e.g., touch-sensitive surface 651 or a touch-sensitive surface of a touch-screen display 650, FIG. 6B). FIG. 7L also shows an input movement limit zone or input movement limit perimeter 714, shown as a dashed line circle or other shape surrounding the focus selector 707. Typically, input movement limit perimeter 714 is not actually displayed, and instead input movement limit perimeter 714 represents an input movement limit utilized by one or more of the gesture recognizers. As shown in FIG. 7L, the intensity of the user input does not satisfy any of the three intensity thresholds I_(L), I_(M) and I_(H).

When the input corresponding to focus selector 707 moves from the position shown in FIG. 7L to the position shown in FIG. 7M, the input has moved across the touch-sensitive surface by at least a predefined distance, as reflected by focus selector 707 having moved at least partially past input movement limit perimeter 714. As a result, the graphical user interface 706 pans or scrolls by an amount corresponding to the distance moved by the input on the touch-sensitive surface. More generally, in response to the input moving across the touch-sensitive surface by at least the predefined distance, a second operation is performed. In some embodiments, the second operation includes scrolling at least a portion of the user interface.

Further, as shown in FIG. 7M, in response to the input moving across the touch-sensitive surface by at least the predefined distance, the reveal gesture recognizer (R), preview gesture recognizer (P), and commit gesture recognizer (C) all transition to the Failed state, and the pan gesture recognizer (S) transitions to the Began state.

In FIG. 7N, the input continues to move across the touch-sensitive surface, as represented by further movement of focus selector 707, which is not completely outside input movement limit perimeter 714. In response to this movement of the input, the pan gesture recognizer (S) transitions to the Changed state and user interface 706 is further scrolled upwards compared with its position in FIG. 7M.

It is noted that intensity of the input in FIGS. 7L, 7M and 7N remains below the first intensity threshold I_(L). Consequences of the intensity of the input satisfying the first intensity threshold I_(L) are addressed below in the discussion of FIGS. 7O-7S and other subsequent figures.

In FIG. 7O, after the input, as represented by focus selector 707, has already moved beyond the input movement limit perimeter 714 with an intensity that does not satisfy the first intensity threshold I_(L), the intensity of the input increases so as to satisfy the first intensity threshold I_(L), as shown in user input intensity graph 70. Satisfaction of the first intensity threshold I_(L) is indicated by a changed appearance of focus selector 707. However, despite the user input now satisfying the first intensity threshold I_(L), the reveal gesture recognizer (R), preview gesture recognizer (P), and commit gesture recognizer (C) all remain in the Failed state, and the pan gesture recognizer (S) remains in the Changed state. It is noted that, typically, once a gesture recognizer transitions to the Failed state, it cannot transition to any other state, such as the Recognized state or Began State, until the user input ceases (i.e., until the user lifts their finger or stylus or other instrument off the touch-sensitive surface).

In some circumstances, user interface 706 transitions from the state shown in FIG. 7L to the state shown in FIG. 7P, in response to the intensity of the input satisfying the first intensity threshold I_(L) prior to the user input moving across the touch-sensitive surface by at least the predefined distance. For example, in FIG. 7P, the input has not moved or has remained at substantially the same location, since the initial contact with the touch-sensitive surface represented by FIG. 7L. In response to the input satisfying intensity input criteria including that the input satisfies the first intensity threshold, a first operation is performed. In this example, the first operation includes blurring user interface 706, or transitioning user interface 706 to a blur state, excluding the user interface object 708 corresponding to the position of the user input, which is not blurred.

Furthermore, in some embodiments, in response to the input satisfying intensity input criteria including that the input satisfies the first intensity threshold, the preview gesture recognizer (P) transitions from the Possible state to the Began state, and performance of the first operation, discussed above, occurs in response to the preview gesture recognizer (P) transitioning to the Began state.

Further, as shown in FIG. 7P, in response to the input remaining at substantially its initial location (i.e., not moving across the touch-sensitive surface by at least the predefined distance) and the input satisfying intensity input criteria including that the input satisfies the first intensity threshold, the preview gesture recognizer (P), commit gesture recognizer (C), and the pan gesture recognizer (S) all remain in the Possible state.

The input on the touch-sensitive surface represented by focus selector 707 in FIG. 7P is sometimes called a first portion of the input, and the subsequent portion of the same input shown in FIG. 7Q is sometimes called a second portion of the input. In some circumstances, discussed in more detail with respect to FIGS. 7P and 7Q and with respect to the flowchart illustrated in FIGS. 8A-8E, the first portion of the input is processed with a first gesture recognizer, for example, the reveal gesture recognizer, and the second portion of the input is processed with a second gesture recognizer, for example, the pan gesture recognizer.

In FIG. 7Q, after the preview gesture recognizer (P) transitions from the Possible state to the Began state (as discussed above with reference to FIG. 7P), the input moves by an amount sufficient to satisfy pan criteria, including that the input has moved across the touch-sensitive surface by at least the predefined distance. In response to the input moving by an amount sufficient to satisfy pan criteria, user interface 706 is scrolled by an amount corresponding to the amount of movement of the input across the touch-sensitive surface, the reveal gesture recognizer (R) transitions to the Canceled state, the preview gesture recognizer (P) and commit gesture recognizer (C) transition to the Failed state, and the pan gesture recognizer (S) transitions to the Changed state. In some embodiments, the transition of the pan gesture recognizer (S) to the Changed state is what causes, or enables, the scrolling of user interface 706, or at least a portion of user interface 706.

FIG. 7R corresponds to the FIG. 7H, but with a pan gesture recognizer (S) in place of a tap gesture recognizer (T). In FIG. 7R, the pan gesture recognizer (S) is in the Failed state due to a lack of movement of the input since its initial contact with the touch-sensitive surface and the transitioning of preview gesture recognizer (P) to the Began state (see FIG. 7G) or Changed state (see FIGS. 7H and 7R). An arrow above focus selector 707 indicates that the input has begun to move, in this example in the upward direction indicated by the arrow.

Further, it is noted that in FIG. 7R, the input satisfies intensity input criteria including that the input satisfies the second intensity threshold I_(M), and as a result the preview gesture recognizer (P) has transitioned to the Began state (see FIG. 7G) or Changed state (see FIGS. 7H and 7R).

FIG. 7S, which shows movement of the input and its corresponding focus selector 707 from the position shown in FIG. 7R to the position shown in FIG. 7S. Despite this movement of the input, which can be assumed for purposes of this discussion to be movement across the touch-sensitive surface by more than the predefined distance, the reveal gesture recognizer (R) and the preview gesture recognizer (P) remain in the Changed state, the commit gesture recognizer (C) remains in the Possible state and the pan gesture recognizer (S) remains in the Failed state. In some embodiments, the reason that the pan gesture recognizer (S) remains in the Failed state is that once a gesture recognizer transitions to the Failed state, it cannot transition to any other state, such as the Recognized state or Began State, until the user input ceases (i.e., until the user lifts their finger or stylus or other instrument off the touch-sensitive surface).

In some embodiments, in conjunction with displaying preview area 712 (e.g., in response to displaying preview area 712), a (new) second pan gesture recognizer is initiated for preview area 712. Thus, in such embodiments, although the pan gesture recognizer (S) is in the Failed state, preview area 712 responds to a pan gesture (e.g., preview area 712 is moved across display 650 in accordance with the pan gesture, using the second pan gesture recognizer, independent of mail application user interface 706 such that mail application user interface 706 remains stationary while preview area 712 is moved across display 650, which is different from the scroll operation associated with the pan gesture recognizer (S) as shown in FIGS. 7O-7P).

FIG. 7T is similar to FIG. 7A, except that the tap gesture recognizer (T) has been replaced by a long press gesture recognizer (L), and focus selector 709 has replaced focus selector 705. The intensity of the input corresponding to focus selector 709 does not satisfy (e.g., is below) the first intensity threshold I_(L), and the amount of time that has elapsed since the initial contact of the input with the touch-sensitive surface is less than a first predefined time period corresponding to time 7116.

FIG. 7U shows that the input has remained in contact with the touch-sensitive surface for the first predefined time period, corresponding to time 7116, and has remained at an intensity that does not satisfy (e.g., is below) the first intensity threshold I_(L). In some embodiments, as shown in FIG. 7U, in accordance with a determination that the input satisfies long press criteria including that the input remains below the first intensity threshold during the first predefined time period, the long press gesture recognizer transitions to the Began state, and the reveal gesture recognizer (R), the preview gesture recognizer (P) and the commit gesture recognizer (C) transition to the Failed state.

Furthermore, in some embodiments, as shown in FIG. 7U, in accordance with the determination that the input satisfies long press criteria including that the input remains below the first intensity threshold during the first predefined time period, a second operation is performed. In the example shown in FIG. 7U, the second operation includes displaying a menu 716 of items related to the object 708 corresponding to a current position of the focus selector 709.

FIG. 7V shows a change in user interface 706 from the view shown in FIG. 7T, in response to an input that satisfies intensity input criteria, including that the input satisfies a first intensity threshold (e.g., I_(L)) during a first predefined time period (e.g., the time period ending at time 7116). As shown in FIG. 7V, intensity of the input has increased above the first intensity threshold I_(L). In response, the reveal gesture recognizer (R) transitions from the Possible state, as shown in FIG. 7T, to the Began state, as shown in FIG. 7V. In some embodiments, in response to the input satisfying intensity input criteria including that the input satisfies the first intensity threshold, a first operation is performed. In this example, the first operation includes blurring user interface 706, or transitioning user interface 706 to a blur state, excluding the user interface object 708 corresponding to the position of the user input, which is not blurred.

FIG. 7W shows a change in user interface 706 from the view shown in FIG. 7V, in response to an input that satisfies intensity input criteria, including that the input remains below a second intensity threshold (e.g., I_(M)) during a first predefined time period (e.g., the time period ending at time 7116). In some embodiments, in accordance with a determination that the input satisfies long press criteria including that the input remains below the second intensity threshold during the first predefined time period, a second operation is performed. In the example shown in FIG. 7W, the second operation includes displaying a menu 716 of items related to the object 708 corresponding to a current position of the focus selector 709.

FIG. 7X shows a change in user interface 706 from the view shown in FIG. 7V, in response to an input that satisfies intensity input criteria, including that the input satisfies a second intensity threshold (e.g., I_(M)) during a first predefined time period (e.g., the time period ending at time 7116). In some embodiments, in accordance with a determination that the input satisfies intensity input criteria including that the input satisfies the second intensity threshold during the first predefined time period, a third operation is performed. In the example shown in FIG. 7X, the third operation is displaying a preview 712 of information corresponding to the user interface object 708 over which the focus selector 709 is positioned. Furthermore, in some embodiments, in accordance with a determination that the input satisfies intensity input criteria including that the input satisfies the second intensity threshold during the first predefined time period, the preview gesture recognizer (P) transitions to the Began state and the long press gesture recognizer (L) transitions to the Failed state. In some embodiments, the transition of the preview gesture recognizer (P) transitions to the Began state causes the long press gesture recognizer (L) to transition to the Failed state.

FIG. 7Y shows user interface 706 after the long press gesture recognizer has already transitioned to the Failed state, and the input has continued to satisfy a first (or second) intensity threshold during the first predefined time period (e.g., the time period ending at time 7116).

Despite the continuation of the input through the first predefined time period, the long press gesture recognizer (L) remains in the failed state. Further, in this example, the reveal gesture recognizer (R) remains in the Changed state, the preview gesture recognizer (P) transitions to the Changed state, and the commit gesture recognizer (C) remains in the Possible state. In some embodiments, the reason that the long press gesture recognizer (L) remains in the Failed state is that once a gesture recognizer transitions to the Failed state, it cannot transition to any other state, such as the Recognized state or Began State, until the user input ceases (i.e., until the user lifts their finger or stylus or other instrument off the touch-sensitive surface).

FIG. 7Z shows a change in user interface 706 from the view shown in FIG. 7T, in response to an input that fails to satisfy a first intensity threshold during a first predefined time period (e.g., the time period ending at time 7116), and ceases to remain on the touch-sensitive surface during the first predefined time period. In response to the input that fails to satisfy a first intensity threshold during a first predefined time period, and ceases to remain on the touch-sensitive surface during the first predefined time period, the reveal gesture recognizer (R), the preview gesture recognizer (P), the commit gesture recognizer (C), and the long press gesture recognizer (L) all transition to the Failed state.

FIG. 7AA shows a view of user interface 706 similar to the view shown in FIG. 7L, except that the pan gesture recognizer (S) has been replaced by the long press gesture recognizer (L), and focus selector 707 has been replaced by focus selector 709. FIG. 7AA, like FIG. 7L, shows an input movement limit zone or input movement limit perimeter 714, shown as a dashed line circle or other shape surrounding focus selector 709. Typically, input movement limit perimeter 714 is not actually displayed, and instead input movement limit perimeter 714 represents an input movement limit utilized by one or more of the gesture recognizers.

FIG. 7BB shows a change in user interface 706 from the view shown in FIG. 7AA. When the input corresponding to focus selector 709 moves from the position shown in FIG. 7AA to the position shown in FIG. 7BB, the input has moved across the touch-sensitive surface by at least a predefined distance, as reflected by focus selector 709 having moved at least partially past input movement limit perimeter 714. As a result, the graphical user interface 706 pans or scrolls by an amount corresponding to the distance moved by the input on the touch-sensitive surface. More generally, in response to the input moving across the touch-sensitive surface by at least the predefined distance, a second operation is performed. In some embodiments, the second operation includes scrolling at least a portion of the user interface.

Further, as shown in FIG. 7AA, in response to the input moving across the touch-sensitive surface by at least the predefined distance, the reveal gesture recognizer (R), the preview gesture recognizer (P), the commit gesture recognizer (C) and the long press gesture recognizer (L) all transition to the Failed state.

FIG. 7CC shows a change in user interface 706 from the view shown in FIG. 7BB. In FIG. 7CC, after the preview gesture recognizer (P), the commit gesture recognizer (C) and the long press gesture recognizer (L) have all transitioned to the Failed state, the intensity of the input either increases so as to satisfy the first predefined threshold I_(L) or even the first predefined threshold I_(M), as indicated by intensity profile 7118, or the input remains in contact with the touch sensitive screen, but below the first intensity threshold, during the first predefined time period (e.g., the time period ending at time 7116), as indicated by intensity profile 7120. In either circumstance, the reveal gesture recognizer (R), the preview gesture recognizer (P), the commit gesture recognizer (C) and the long press gesture recognizer (L) all remain in the Failed state. In some embodiments, the reason that reveal gesture recognizer (R), the preview gesture recognizer (P), the commit gesture recognizer (C) and the long press gesture recognizer (L) all remain in the Failed state is that once a gesture recognizer transitions to the Failed state, it cannot transition to any other state, such as the Recognized state or Began State, until the user input ceases (i.e., until the user lifts their finger or stylus or other instrument off the touch-sensitive surface).

FIG. 7DD shows a view of user interface 706 similar to the view shown in FIG. 7T, except that the pan gesture recognizer (S) has been replaced by the tap gesture recognizer (T), and focus selector 711 is located on email address 718. When the long press gesture recognizer (L) is used without a pan gesture recognizer (S) (e.g., the long press gesture recognizer (L) is the only gesture recognizer associated with the email address, or the long press gesture recognizer (L) and one or more other gesture recognizers, other than the pan gesture recognizer (S), are associated with the email address), a time period ending at time 7122 is used instead of a time period ending at time 7116, in determining whether the long press gesture recognizer (L) should transition to another state, such as the Began state.

In FIG. 7EE, in accordance with the determination that the input remains on the touch-sensitive surface during the time period ending at time 7122, a predefined operation of displaying menu 716 of items related to object 718 is performed regardless of whether the input remains on the touch-sensitive surface for the entire duration of the time period ending at time 7116.

FIG. 7FF shows that intensity 7204 of the input corresponding to focus selector 713 is detected and sent to application-independent module 220. In response to receiving intensity 7204, application-independent module 7220 sends one or more event objects 194 to application-specific module 230.

Event object 194 includes characteristic intensity 7206 that is based on detected intensity 7204. In some embodiments, event object 1904 also includes reference intensity 7208. For example, in some embodiments, characteristic intensity 7206 is a normalized intensity value that corresponds to detected intensity 7204 divided by reference intensity 7208. In some embodiments, reference intensity 7208 corresponds to a maximum intensity that can be detected by the one or more intensity sensors. In some embodiments, reference intensity 7208 is a predefined intensity level for normalizing detected intensity 7204. Characteristic intensity 7206 typically has a range between 0 and 1. Because application-specific module 230 receives characteristic intensity 7206 instead of detected intensity 7204, application-specific module 230 is configured to receive and respond to intensity information that is independent from variations among intensity sensors. Thus, application-specific module 230 does not need to include instructions for handling variations among intensity sensors, and therefore, the size of the application-specific module 230 is reduced, and the performance of the application-specific module 230 is improved.

In some embodiments, when sensitivity 7210 is set, characteristic intensity 7206 is multiplied by sensitivity value 7210. In some embodiments, sensitivity 7210 has a default value of 1. However, for example, when sensitivity 7210 has a value of 2, characteristic intensity 7206 is doubled.

In FIG. 7GG, an exemplary settings user interface is shown on display 650. The settings user interface shown in FIG. 7GG includes area 720 with multiple intensity settings (e.g., low, medium, and high intensity settings). User input intensity graph 702 in FIG. 7GG shows that characteristic intensity 7304, which follows detected intensity 7302, is used when the low sensitivity setting is selected. To facilitate the comparison of intensity values, a reference intensity of 1 is used for user input intensity graph 702 in FIG. 7GG. When the medium setting is selected, characteristic intensity 7306, which has a higher intensity value than characteristic intensity 7304 (e.g., characteristic intensity 7306 is two times characteristic intensity 7304), is used; and, when the high setting is selected, characteristic intensity 7308, which has a higher intensity value than characteristic intensity 7306 (e.g., characteristic intensity 7308 is three times characteristic intensity 7304), is used.

FIG. 7HH is similar to FIG. 7GG, except that the settings user interface includes area 722 with a plurality of intensity setting options (e.g., more than three levels of intensity setting options). Although there are more than three levels of intensity setting options, user input intensity graph 702 in FIG. 7HH shows three levels of characteristic intensity lines (e.g., 7304, 7306, and 7308) so as not to obscure the understanding of user input intensity graph 702.

FIG. 7II shows that multiple focus selectors (e.g., 715 and 717) are concurrently detected, and intensities of respective focus selectors are separately determined. Application-independent module 220 receives intensity 7204 of focus selector 715 and intensity 7212 of focus selector 717, and sends respective event objects 194 and 7194 to application-specific module 230. Event object 194 corresponds to focus selector 715 and includes characteristic intensity 7206 of focus selector 715 as well as reference intensity 7208. The same reference intensity 7208 is used to normalize intensities of multiple touches. Thus, event object 7194, corresponding to focus selector 717, also includes the same reference intensity 7208 as well as characteristic intensity 7214 of focus selector 717 in event object 194.

FIG. 7JJ shows a depinch gesture by focus selectors 715 and 717 on mail application user interface 706. In FIG. 7JJ, state machines 704 for gesture recognizers show that mail application user interface 706 is associated with two pinch gesture recognizers: a first pinch gesture recognizer (N₁) for which a first intensity threshold (e.g., I₁) is specified (e.g., by e-mail client module 140 in FIG. 1A) and a second pinch gesture recognizer (N₂) for which an intensity threshold is not specified (e.g., by e-mail client module 140 in FIG. 1A).

User input intensity graph 702 in FIG. 7KK shows that the pinch or depinch gesture by focus selectors 715 and 717 satisfies the intensity threshold I₁. In response, the first pinch gesture recognizer (N₁) transitions to the Recognized state and a corresponding operation (e.g., displaying mail application user interface 724, showing an inbox view) is performed. In addition, the second pinch gesture recognizer (N₂) transitions to the Failed state (e.g., because the first pinch gesture recognizer (N₁) has transitioned to the Recognized state).

User input intensity graph 702 in FIG. 7LL shows a case in which the pinch or depinch gesture by focus selectors 715 and 717 does not satisfy the intensity threshold I₁. In response, the second pinch gesture recognizer (N₂) transitions to the Recognized state and a corresponding operation (e.g., displaying a zoomed-in view) is performed. In addition, the first pinch gesture recognizer (N₁) transitions to the Failed state (e.g., because the second pinch gesture recognizer (N₂) has transitioned to the Recognized state).

In FIG. 7MM, state machines 704 show that mail application user interface 706 is associated with the two pinch gesture recognizers (N₁) and (N₂), and a two-finger pan gesture recognizer (2S) for which a second intensity threshold (e.g., I₂) is specified (e.g., by e-mail client module 140 in FIG. 1A). FIG. 7MM also shows a two-finger pan gesture by focus selectors 719 and 721 on mail application user interface 706.

User input intensity diagram 702 in FIG. 7NN shows that the two-finger pan gesture satisfies the second intensity threshold. The two-finger pan gesture recognizer (2S) transitions to the Began state, and a corresponding operation (e.g., overlaying review window 726 showing a review of the linked website on mail application user interface 706) is performed. The first pinch gesture recognizer (N₁) and the second pinch gesture recognizer (N₂) transition to the Failed state (e.g., because the two-finger pan gesture recognizer (2S) has transitioned to the Recognized state).

FIG. 7OO shows browser application user interface 710 and a depinch gesture by focus selectors 723 and 725 on an address window of browser application user interface 710. State machines 704 for gesture recognizers in FIG. 7OO show that the address window of browser application user interface 710 is associated with a third pinch gesture recognizer (N₃) for which a third intensity threshold (e.g., I₃) is specified (e.g., by browser module 147 in FIG. 1A). User input intensity graph 702 in FIG. 7OO shows that the intensity of focus selectors 723 and 725 satisfy the third intensity threshold I₃, and the third pinch gesture recognizer (N₃) has transitioned to the Began state. The first pinch gesture recognizer (N₁) and the second pinch gesture recognizer (N₂) remain in the Possible state, because the third pinch gesture recognizer (N3) is not associated with the view, which corresponds to the first pinch gesture recognizer (N₁) and the second pinch gesture recognizer (N₂).

FIG. 7PP shows that focus selectors 723 and 725 cease to be detected. However, because focus selectors 723 and 725 have satisfied the third intensity threshold I₃, the third pinch gesture recognizer (N₃) has transitioned to the Recognized state, and a corresponding operation (e.g., displaying tabs management view 728) is performed.

User input intensity graph 702 in FIG. 7QQ shows a case in which the intensity of focus selectors 723 and 725 does not satisfy the third intensity threshold (e.g., I₃). Thus, the third pinch gesture recognizer (N₃) transitions to the Failed state, and no action associated with the third pinch gesture recognizer is performed (e.g., tabs management view 728 shown in FIG. 7PP is not displayed).

FIG. 7RR shows focus selector 727 over user interface object 708 of mail application user interface 706.

User input intensity graph 702 in FIG. 7RR shows first timing criteria (e.g., an input needs to remain on the touch-sensitive surface for a period ending at time 7124) and first intensity input criteria (e.g., an input needs to satisfy an intensity threshold I_(L) at time 7124 or thereafter), both of which need to be satisfied for performing a first predefined operation (e.g., dimming or blurring at least a portion of the user interface to provide a hint of an impending display of a preview window, or alternatively, displaying a preview window).

In FIG. 7RR, an input that follows intensity pattern 7126 satisfies both the first timing criteria (because the input remains on at least for a time period ending at time 7124) and the first intensity input criteria (because the input satisfies the intensity threshold I_(L) at time 7124). Thus, the first predefined operation (e.g., dimming or blurring at least a portion of the user interface to provide a hint of an impending display of a preview window) is performed at time 7124.

An input that follows intensity pattern 7128 satisfies both the first timing criteria (because the input remains on at least for a time period ending at time 7124) and the first intensity input criteria (because intensity of the input increases and satisfies the intensity threshold I_(L) after time 7124). Thus, the first predefined operation (e.g., dimming or blurring at least a portion of the user interface to provide a hint of an impending display of a preview window) is performed when intensity of the input satisfies the intensity threshold I_(L).

An input that follows intensity pattern 7130 does not satisfy the first intensity input criteria, because intensity of the input does not satisfy the intensity threshold I_(L) at any time. Although the first timing criteria are satisfied (because the input remains on the touch-sensitive surface at least for a period ending at time 7124), the first predefined operation (e.g., dimming or blurring at least a portion of the user interface to provide a hint of an impending display of a preview window) is not performed.

For an input that follows intensity pattern 7131 or intensity pattern 7132, although its input satisfies the intensity threshold I_(L), the input does not satisfy the first intensity input criteria, because intensity of the input does not satisfy the intensity threshold I_(L) at or subsequent to time 7124. The first timing criteria are not satisfied, because the input does not remain on the touch-sensitive surface at least for a period ending at time 7124. Thus, the first predefined operation (e.g., dimming or blurring at least a portion of the user interface to provide a hint of an impending display of a preview window) is not performed.

In some embodiments, because the input following intensity pattern 7132 is released before time 7134, a different operation (e.g., a tap gesture operation) is performed if the different operation is associated with user interface object 708. However, the input following intensity pattern 7131 is released after time 7134, the tap gesture operation is not performed in response to the input following intensity pattern 7131. In some embodiments, time 7134 corresponds to time 7002 shown in FIG. 7B.

FIG. 7SS shows mail application user interface 706, which is at least partially dimmed or blurred. In some embodiments, the partial dimming or blurring provides a visual cue indicating that a further increase in intensity of the input will initiate display of a preview window.

User input intensity graph 702 in FIG. 7TT shows second timing criteria (e.g., an input needs to remain on the touch-sensitive surface for a period ending at time 7136) and second intensity input criteria (e.g., an input needs to satisfy an intensity threshold I_(M) at time 7136 or thereafter), both of which need to be satisfied for performing a second predefined operation (e.g., displaying a preview window). In some embodiments, time 7136 is distinct from time 7124, as shown in FIG. 7TT. In some embodiments, time 7136 and time 7124 are identical.

An input that follows intensity pattern 7128 satisfies both the second timing criteria (because the input remains on the touch-sensitive surface at least for a time period ending at time 7136) and the second intensity input criteria (because intensity of the input increases and satisfies the intensity threshold I_(M) after time 7136). Thus, the second predefined operation (e.g., displaying preview window 712) is performed when intensity of the input satisfies the intensity threshold I_(M).

An input that follows intensity pattern 7138 satisfies both the second timing criteria (because the input remains on the touch-sensitive surface at least for a time period ending at time 7136) and the second intensity input criteria (because the input satisfies the intensity threshold I_(M) at time 7136). Thus, the second predefined operation (e.g., displaying a preview window 712) is performed at time 7136.

However, an input that follows intensity pattern 7140 does not satisfy the second intensity input criteria, because the input does not satisfy the intensity threshold I_(M) at any time. Although the input satisfies the second timing criteria (e.g., the input remains on the touch-sensitive surface for a time period ending at time 7136), because the second intensity input criteria are not satisfied, the second predefined operation (e.g., displaying a preview window 712) is not performed.

An input that follows intensity pattern 7142 does not satisfy the second intensity input criteria. Although intensity of the input temporarily satisfies the intensity threshold I_(M), the intensity of the input decreases below the intensity threshold I_(M) before time 7136. Because the input does not satisfy the intensity threshold I_(M) at time 7136 or thereafter, the second intensity input criteria are not satisfied. Although the input satisfies the second timing criteria (e.g., the input remains on the touch-sensitive surface for a time period ending at time 7136), because the second intensity input criteria are not satisfied, the second predefined operation (e.g., displaying a preview window 712) is not performed.

User input intensity graph 702 in FIG. 7UU shows that, in some embodiments, when intensity of the input decreases below a reference intensity I_(R), the timing criteria are reset (e.g., instead of starting the time period from when the initial contact is detected, the time period restarts from when the intensity of the input decreases below the reference intensity). For example, in FIG. 7UU, the input remains on the touch-sensitive surface for a time period ending at time 7124 and the intensity of the input at time 7124 satisfies the intensity threshold I_(L). However, the first predefined operation is not performed at time 7124, because the first timing criteria are reset when the intensity of the input falls below the reference intensity I_(R) at time 7146. The first timing criteria are satisfied after the input remains on the touch-sensitive surface for time period p₁ ending at time 7148, and the first intensity input criteria are satisfied at time 7148, because the input satisfies the intensity threshold I_(L) at time 7148. Thus, the first predefined operation (e.g., dimming or blurring at least a portion of the user interface to provide a hint of an impending display of a preview window) is performed at time 7148.

In some embodiments, the reference intensity I_(R) is determined by using a representative intensity (e.g., a peak intensity) of the input and an intensity margin I_(margin). For example, the reference intensity corresponds to the intensity margin I_(margin) below the representative intensity (e.g., the peak intensity) of the input.

User input intensity graph 702 in FIG. 7VV shows that when intensity of the input decreases below a first reference intensity I_(R1), which corresponds to the intensity margin I_(margin) below the representative intensity (e.g., the peak intensity) of the input. In some embodiments, when the intensity of the input decreases below the first reference intensity I_(R1), the first timing criteria are reset and a new (second) reference intensity I_(R2) is determined so that the second reference intensity I_(R2) corresponds to the intensity margin I_(margin) below the first reference intensity I_(R1). When the intensity of the input decreases even below the second reference intensity I_(R2) at time 7150, the first timing criteria are again reset, and the first time period p1 ends at time 7152. The first timing criteria are satisfied, because the input remains on the touch-sensitive surface through the end of first time period p1 at time 7152, and the first intensity input criteria are satisfied, because the input satisfies the intensity threshold I_(L) at the end of the first time period p1 at time 7152. Thus, the first predefined operation (e.g., dimming or blurring at least a portion of the user interface to provide a hint of an impending display of a preview window) is performed at time 7152.

Although FIGS. 7UU and 7VV illustrate resetting the first timing criteria, in some embodiments, the second timing criteria are reset in an analogous manner. For brevity, such details are omitted herein.

FIG. 7WW shows focus selector 729 over user interface object 708 of mail application user interface 706.

User input intensity graph 702 in FIG. 7WW shows first intensity threshold component 7154 for a predefined operation (e.g., replacing display of mail application user interface 706 with browser application user interface 710). First intensity threshold component 7154 has initially high value I_(H) and decays over time, which reduces the chance of immediately performing the predefined operation with an unintentionally strong input during an initial time period. However, this does not prevent the predefined operation completely. If the input has a sufficient intensity, it can still satisfy first intensity threshold component 7154 and initiate the predefined operation. By decaying (e.g., reducing) first intensity threshold component 7154 overtime, it becomes easier to perform the predefined operation after the input remains on the touch-sensitive surface for a while.

In FIG. 7WW, an input following intensity pattern 7156 satisfies first intensity threshold component 7154, and initiates performance of the predefined operation (e.g., replacing display of mail application user interface 706 with browser application user interface 710).

An input following intensity pattern 7158 (e.g., a short strong tap gesture) does not satisfy first intensity threshold component 7154, because the intensity of the input quickly drops and the input is released before first intensity threshold component 7154 begins to decay.

In some embodiments, first intensity threshold component 7154 begins to decay immediately from an initial detection of the input. In some embodiments, first intensity threshold component 7154 begins to decay after a predefined time interval p3 from the initial detection of the input, as shown in FIG. 7WW.

User input intensity graph 702 in FIG. 7XX shows that when the intensity of the input falls below the reference intensity I_(R) at time 7162, first intensity threshold component 7164 begins the decay at time 7162, even before the predefined time interval p3 has elapsed. Thus, in FIG. 7XX, an input following intensity pattern 7160 satisfies first intensity threshold component 7164, and the predefined operation (e.g., replacing display of mail application user interface 706 with browser application user interface 710) is performed.

FIG. 7YY illustrates activation intensity threshold 7170, which is a sum of first intensity threshold component 7154 (described above with respect to FIG. 7WW) and second intensity threshold component 7168. As shown in FIG. 7YY, second intensity threshold component 7168 follows intensity of input 7166 with a delay. Second intensity threshold component 7168 reduces unintentional triggering of the predefined operation due to minor fluctuations in the intensity of input 7166 over time. For example, gradual changes in the intensity of input 7166 are less likely to trigger the predefined operation. In FIG. 7YY, input 7166 satisfies activation intensity threshold 7170 at time 7167, and the predefined operation (e.g., replacing display of mail application user interface 706 with browser application user interface 710) is performed at time 7167.

FIG. 7ZZ illustrates activation intensity threshold 7174, which is similar to activation intensity threshold 7170 (in FIG. 7YY) except that a first intensity threshold component of activation intensity threshold 7174 begins to decay at time 7176, which corresponds to a predefined time interval p3 after time 7124 when the first and second predefined operations are performed. In FIG. 7ZZ, input 7172 satisfies activation intensity threshold 7174 at time 7173, and the predefined operation (e.g., replacing display of mail application user interface 706 with browser application user interface 710) is performed at time 7173.

FIG. 7AAA illustrates activation intensity threshold 7180, which decays over time, while input 7178 satisfies the intensity threshold I_(M) (and the second predefined operation is performed). The intensity of input 7178 decreases below the intensity threshold I_(M) and I_(L), which in some embodiments does not undo the second predefined operation. Because activation intensity threshold 7180 has decayed significantly over time, an increase in the intensity of input 7178 satisfies activation intensity threshold 7180 at time 7179, even though activation intensity threshold 7180 is below the intensity threshold I_(M).

FIG. 7BBB shows the same activation intensity threshold 7180 and input 7178 shown in FIG. 7AAA. FIG. 7BBB also shows that activation intensity threshold 7180 does not fall below baseline threshold 7182, which reduces unintentional triggering of the predefined operation (e.g., replacing display of mail application user interface 706 with browser application user interface 710).

FIGS. 8A-8E are flow diagrams illustrating method 800 of disambiguating a long press input and a deep press input in accordance with some embodiments. Method 800 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface (e.g., the touch-sensitive surface is a trackpad). Some operations in method 800 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 800 provides an enhanced way to process touch inputs with instructions. Method 800 improves efficiency in processing touch inputs.

The device displays (802) a first user interface. While displaying the first user interface, the device detects (804) an input on the touch-sensitive surface. Examples of the first user interface and responses to the input on the touch-sensitive surface are described above with reference to FIGS. 7T through 7CC. In some embodiments, the first user interface includes a plurality of user interface objects, the input is detected while a focus selector (e.g., focus selector 709, FIG. 7T) is over a first user interface object (e.g., object 708, FIG. 7T) of the plurality of user interface objects, and the first user interface object is associated with at least a first gesture recognizer (e.g., a preview gesture recognizer) and a second gesture recognizer (e.g., a long press gesture recognizer).

In response to detecting the input (808) while displaying the first user interface, the device performs (810) a first operation (e.g., blurring a user interface, as shown in FIGS. 7D and 7V) in accordance with a determination that the input satisfies intensity input criteria including that the input satisfies a first intensity threshold during a first predefined time period. On the other hand, in response to detecting the input (808) while displaying the first user interface, the device performs (812) a second operation (e.g., displaying a menu or menu view 716, FIG. 7U) that is distinct from the first operation in accordance with a determination that the input satisfies long press criteria including that the input remains below the first intensity threshold during the first predefined time period. As noted above, in some embodiments the second operation includes displaying (830) a menu or menu view (e.g., menu view 716, FIG. 7U).

In some embodiments, the intensity input criteria include (840) that the input (while remaining in contact with the touch-sensitive surface) does not move across the touch-sensitive surface by more than a predefined distance (e.g., as discussed above with reference to input movement limit perimeter 714 in FIGS. 7L-7Q, and 7AA-7CC), and the long press criteria include (842) that the contact in the input does not move across the touch-sensitive surface by more than the predefined distance.

In some embodiments, method 800 includes, in accordance with a determination that the input does not satisfy the intensity input criteria and does not satisfy the long press criteria, forgoing (814) the first operation and the second operation.

In some embodiments, detecting (804) the input on the touch-sensitive surface includes detecting (806, 850) a first portion of the input and a second portion of the input that is subsequent to the first portion of the input. Furthermore, in some such embodiments, method 800 includes, in response (852) to detecting the first portion of the input on the touch-sensitive surface (e.g., detecting an initial contact of the input with the touch-sensitive surface), identifying a first set of gesture recognizers that correspond to at least the first portion of the input as candidate gesture recognizers, the first set of gesture recognizers including a first gesture recognizer (e.g., a preview gesture recognizer) and a second gesture recognizer (e.g., a long press gesture recognizer).

Further, in the aforementioned embodiments, in response to detecting the second portion of the input on the touch-sensitive surface, the device performs (854) the first operation, including processing the input with the first gesture recognizer (e.g., the preview gesture recognizer) in accordance with the determination that the input satisfies the intensity input criteria. In some embodiments, the first intensity threshold (e.g., I_(M) in FIG. 7T) is distinct from an input detection intensity threshold (e.g., I_(L) in FIG. 7T). In some embodiments, processing of the input with the first gesture recognizer also requires a determination that the second gesture recognizer does not recognize a gesture that corresponds to the input. In some embodiments, processing of the input with the first gesture recognizer also requires a determination that the second gesture recognizer has failed to recognize a gesture that corresponds to the input (i.e., that the second gesture recognizer has transitioned to the Failed state, as discussed above with reference to FIGS. 7X and 7Y).

Further, in the aforementioned embodiments, in response to detecting the second portion of the input on the touch-sensitive surface, the device performs (854) the second operation, including processing the input with the second gesture recognizer (e.g., with the long press gesture recognizer (L), FIGS. 7T-7U) in accordance with the determination that the input satisfies the long press criteria. In some embodiments, processing of the input with the second gesture recognizer also requires a determination that the first gesture recognizer has failed to recognize a gesture that corresponds to the input (e.g., the intensity of the input detected by the one or more sensors does not satisfy the first intensity threshold during the predefined time period). In the example discussed above with respect to FIG. 7U, the preview gesture recognizer has transitioned to the Failed state in accordance with a determination by the device that the intensity of the input detected by the one or more sensors does not satisfy the first intensity threshold (e.g., I_(M), FIG. 7U) during the predefined time period (e.g., the time period ending at time 7116, FIG. 7U).

As indicated above, in some embodiments the first gesture recognizer (e.g., the preview gesture recognizer) is an intensity-based gesture recognizer and the second gesture recognizer is a long press gesture recognizer (860). In some embodiments, the second gesture recognizer (e.g., the long press gesture recognizer) recognizes a particular type or set of gestures independent of intensity of the input.

In some embodiments or circumstances, the input includes (862) a third portion of the input that is subsequent to the second portion of the input, and method 800 includes processing the third portion of the input with the first gesture recognizer. In some embodiments, in accordance with a determination that the input ceases to satisfy the first intensity threshold, the device displays the preview area at a reduced scale (e.g., reduces the size of the preview area), an example of which is shown in the transition from the user interface of FIG. 7H to the user interface of FIG. 7J (i.e., without transitioning through the user interface of FIG. 7I).

In some embodiments, the first set of gesture recognizers includes (864) a third gesture recognizer, such as a reveal gesture recognizer (e.g., gesture recognizer (R) in FIGS. 7A-7CC).

In some embodiments, in response to determining that the input satisfies (866) a second intensity threshold (e.g., a commit intensity threshold I_(H) that is higher than the first intensity threshold I_(M)), the method includes, subsequent to performing the first operation, processing the input with the first gesture recognizer, including replacing display of the first user interface (e.g., user interface 706, FIG. 7H) with a second user interface (e.g., user interface 710, FIG. 7I), and ceasing to display the preview area (e.g., preview area 712, FIG. 7H). In some embodiments, the second user interface includes content that was displayed in the preview area.

In some embodiments, the first set of gesture recognizers includes (868) a fourth gesture recognizer (e.g., a commit gesture recognizer (C), as shown in FIGS. 7A-7CC), and method 800 includes, in response to determining (870) that the input satisfies a second intensity threshold (e.g., a commit intensity threshold I_(H) that is higher than the first intensity threshold I_(M)), processing the input with the fourth gesture recognizer (e.g., the commit gesture recognizer). In some embodiments, processing the input with the fourth gesture recognizer includes replacing display of the first user interface with a second user interface (and ceasing to display the preview area), for example replacing display of user interface 706, FIG. 7H, with user interface 710, FIG. 7I, and ceasing to display preview area 712, FIG. 7H.

In some embodiments, method 800 includes detecting (872) a second input on the touch-sensitive surface, including detecting a first portion of the second input and a second portion of the second input that is subsequent to the first portion of the second input. For example, this may occur while the device is displaying the first user interface or a third user interface that is distinct from the first user interface and the second user interface.

In response to detecting (872) the first portion of the second input on the touch-sensitive surface, the method includes identifying (874) a second set of gesture recognizers that correspond to at least the first portion of the second input, the second set of gesture recognizers including the second gesture recognizer (e.g., the long press gesture recognizer) without the first gesture recognizer (e.g., the preview gesture recognizer). For example, the second input may be positioned over an object for which the first gesture recognizer is not relevant.

Furthermore, in some embodiments, method 800 includes, in response to detecting (876) the second portion of the second input on the touch-sensitive surface, in accordance with a determination that the second input satisfies second long press criteria including that the second input remains on the touch-sensitive surface for a second predefined time period that has a different duration from the first predefined time period (e.g., a longer duration or a shorter duration than the first predefined time period), processing the second input with the second gesture recognizer. For example, in a first user interface in which there is an intensity-based gesture recognizer and a long press gesture recognizer for a same respective object or region, the intensity-based gesture recognizer is given more time to recognize an intensity-based gesture by increasing the delay before the long press gesture recognizer recognizes a long press gesture. In contrast, in a third user interface in which there is an object or user interface region that has a tap/select gesture recognizer and a long press gesture recognizer without an intensity-based gesture recognizer, the tap/select gesture recognizer does not need as much time to recognize a tap/select gesture and thus the delay (i.e., the second predefined time period) before the long press gesture recognizer in third user interface recognizes a long press gesture can be shorter than the delay (i.e., the first predefined time period) required by the long press gesture recognizer for the first user interface before recognizing a long press gesture.

In some embodiments, in response to detecting the first portion of the input, the device performs (880) a third operation. In some embodiments, performing the third operation includes visually distinguishing (882) at least a portion of the first user interface from other portions of the first user interface. For example, the third operation may be blurring the user interface other than an object corresponding to a focus selector, by using a third gesture recognizer (e.g., a reveal gesture recognizer), as shown in FIG. 7V. In some embodiments, if the long press gesture recognizer succeeds after the third operation is performed by the third gesture recognizer, then the third gesture recognizer transitions to the Canceled state and the third operation is reversed (e.g., the blurring is reversed or undone). An example of the latter example is shown in the transition from FIG. 7V to FIG. 7W. On the other hand, if the deep press gesture recognizer (e.g., the preview gesture recognizer) succeeds, then the third operation (the blurring) by the third gesture recognizer (e.g., a reveal gesture recognizer) is canceled, and the first operation (e.g., displaying preview area 712, as shown in FIG. 7X) is performed by the deep press gesture recognizer (e.g., the preview gesture recognizer). In some embodiments, for an object having a reveal gesture recognizer and no long press gesture recognizer, the reveal operation (e.g., the blurring) is not automatically cancelled after the first predefined time period. However, in some such embodiments, for an object having both a reveal gesture recognizer and a long press gesture recognizer, the reveal operation is cancelled when the long press gesture recognizer succeeds.

In some embodiments, method 800 includes performing (884) the first operation (e.g., displaying the preview area) subsequent to performing (880) the third operation (e.g., the blurring) in accordance with the determination that the input satisfies the intensity input criteria (e.g., by reaching or exceeding I_(M)), and performing (886) the second operation (e.g., displaying a menu or menu view, 716, FIG. 7U) in accordance with the determination that the input satisfies the long press criteria. Thus, these determinations and operations are performed while the input remains in contact with the touch-sensitive surface. In some embodiments, while the third gesture recognizer (e.g., a reveal gesture recognizer) is processing inputs (e.g., generating touch events corresponding to the second portion of the input), the first gesture recognizer and the second gesture recognizer are evaluating the second portion of the input to determine whether the input matches gesture recognition criteria for those gesture recognizers. In such embodiments, processing the input with the third gesture recognizer does not block processing the input with the first gesture recognizer and processing the input with the second gesture recognizer.

As mentioned above, in some embodiments, performing the first operation includes (820) displaying a preview area (e.g., preview area 712, FIG. 7H). Furthermore, in some embodiments, performing the second operation includes (830) displaying a menu view (e.g., menu view, 716, FIG. 7U).

In some embodiments, the first intensity threshold is satisfied (822) in response to multiple contacts in the input satisfying the first intensity threshold. For example, in some such embodiments, an intensity of each contact is compared with the first intensity threshold. However, in some other embodiments, the first intensity threshold is satisfied (824) in response to a combination of the intensity applied by a plurality of contacts in the input satisfying the first intensity threshold (e.g., the intensity of multiple contacts is summed or otherwise combined and the resulting combined intensity is compared with the first intensity threshold).

In some embodiments, the first intensity threshold is adjustable (826). For example, in some such embodiments, method 800 includes updating (828) the first gesture recognizer to be activated in response to the intensity of the input satisfying a third intensity threshold that is distinct from the first intensity threshold. In some embodiments, the first intensity threshold is selected from a group of three or more predefined intensity thresholds (e.g., a reveal intensity threshold I_(L), a preview intensity threshold I_(M), and a commit intensity threshold I_(H)). In some embodiments, the third intensity threshold is selected from the group of three or more predefined intensity thresholds.

In some embodiments, the first intensity threshold is selected independent of any predefined intensity thresholds. In some embodiments, the first user interface is a user interface of a particular software application, and the first intensity threshold is selected or specified by the particular software application. In some embodiments, the first intensity threshold is a fixed intensity threshold that does not change while the contact is detected on the touch-sensitive surface. However, in some other embodiments, the first intensity threshold is a dynamic intensity threshold that changes over time based on predefined threshold-adjustment policies based on the activity of the user, and/or the condition of the device, and/or other environmental parameters. Adjustable intensity thresholds are discussed in more detail elsewhere in this document.

It should be understood that the particular order in which the operations in FIGS. 8A-8E have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. For example, in some embodiments, a method performed at an electronic device with a touch-sensitive surface, a display, and one or more sensors to detect intensity of contacts with the touch-sensitive surface includes, while displaying a user interface that corresponds to at least a portion of a web page on the display, detecting a touch input on the touch-sensitive surface at a first location that corresponds to the displayed portion of the web page on the display. The method also includes, while detecting the touch input on the touch-sensitive surface, detecting an intensity of the touch input on the touch-sensitive surface (e.g., with the one or more sensors); determining whether the intensity of the touch input on the touch-sensitive surface has changed from below a first intensity threshold (e.g., a low intensity threshold, such as a mouse down intensity threshold) to above the first intensity threshold; and, in response to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the first intensity threshold to above the first intensity threshold, generating a mouse down event (and optionally, processing instructions in the web page that correspond to a mouse down event). The method further includes, subsequent to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the first intensity threshold to above the first intensity threshold, detecting the intensity of the touch input on the touch-sensitive surface; determining whether the intensity of the touch input on the touch-sensitive surface has changed from below a second intensity threshold (e.g., a high intensity threshold, such as a force down intensity threshold) that is distinct from the first intensity threshold to above the second intensity threshold; and, in response to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the second intensity threshold to above the second intensity threshold, generating a force down event that is distinct from the mouse down event. For brevity, these details are not repeated herein.

Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 900, 1000, 1100, 1200, 1300, 1400, 1500, and 1600) are also applicable in an analogous manner to method 800 described above with respect to FIGS. 8A-8E. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 800 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 900, 1000, 1100, 1200, 1300, 1400, 1500, and 1600). For brevity, these details are not repeated here.

FIGS. 9A-9D are flow diagrams illustrating method 900 of disambiguating a pan gesture input and a deep press input in accordance with some embodiments.

The device displays (902) a first user interface. While displaying the first user interface, the device detects (904) an input on the touch-sensitive surface. Examples of the first user interface and responses to the input on the touch-sensitive surface are described above with reference to FIGS. 7L through 7S. In some embodiments, the first user interface includes a plurality of user interface objects, the input is detected while a focus selector (e.g., focus selector 707, FIG. 7L) is over a first user interface object (e.g., object 708, FIG. 7L) of the plurality of user interface objects, and the first user interface object is associated with at least a first gesture recognizer (e.g., a preview gesture recognizer) and a second gesture recognizer (e.g., a pan gesture recognizer (S)).

In response to detecting the input (908) while displaying the first user interface, the device performs (910) a first operation (e.g., blurring a user interface, as shown in FIGS. 7D and 7P) in accordance with a determination that the input satisfies intensity input criteria including that the input satisfies a first intensity threshold. On the other hand, in response to detecting the input (908) while displaying the first user interface, the device performs (912) a second operation (e.g., panning or scrolling at least a portion of the first user interface, FIG. 7M) that is distinct from the first operation in accordance with a determination that the input satisfies pan criteria including that the input has moved across the touch-sensitive surface by at least a predefined distance (while remaining in contact with the touch-sensitive surface). As noted above, in some embodiments the second operation includes scrolling (930) at least a portion of the first user interface (e.g., as shown in FIG. 7M).

In some embodiments, performing the first operation includes (920) displaying a preview area (e.g., preview area 712, FIGS. 7H, 7R, 7S).

In some embodiments, the intensity input criteria include (922) that the input (while remaining in contact with the touch-sensitive surface) does not move across the touch-sensitive surface by at least the predefined distance (e.g., as discussed above with reference to input movement limit perimeter 714 in FIGS. 7L-7Q, and 7AA-7CC).

In some embodiments, the first intensity threshold is adjustable (924). For example, in some such embodiments, method 900 includes updating (926) the first gesture recognizer to be activated in response to the intensity of the input satisfying a third intensity threshold that is distinct from the first intensity threshold. In some embodiments, the first intensity threshold is selected from a group of three or more predefined intensity thresholds (e.g., a reveal intensity threshold I_(L), a preview intensity threshold I_(M), and a commit intensity threshold I_(H)). In some embodiments, the third intensity threshold is selected from the group of three or more predefined intensity thresholds.

In some embodiments, the first intensity threshold is selected independent of any predefined intensity thresholds. In some embodiments, the first user interface is a user interface of a particular software application, and the first intensity threshold is selected or specified by the particular software application. In some embodiments, the first intensity threshold is a fixed intensity threshold that does not change while the contact is detected on the touch-sensitive surface. However, in some other embodiments, the first intensity threshold is a dynamic intensity threshold that changes over time based on predefined threshold-adjustment policies based on the activity of the user, and/or the condition of the device, and/or other environmental parameters. Adjustable intensity thresholds are discussed in more detail elsewhere in this document.

In some embodiments, method 900 includes, subsequent to performance of the first operation, forgoing (914) performance of the second operation. Similarly, in some embodiments, method 900 includes, subsequent to performance of the second operation, forgoing (916) performance of the first operation.

In some embodiments, detecting (904) the input on the touch-sensitive surface includes detecting (906, 950) a first portion of the input and a second portion of the input that is subsequent to the first portion of the input. Furthermore, in some such embodiments, method 900 includes, in response (952) to detecting the first portion of the input on the touch-sensitive surface (e.g., detecting an initial contact of the input with the touch-sensitive surface), identifying a first set of gesture recognizers that correspond to at least the first portion of the input as candidate gesture recognizers, the first set of gesture recognizers including a first gesture recognizer (e.g., a preview gesture recognizer) and a second gesture recognizer (e.g., a pan gesture recognizer).

In some embodiments or circumstances, the first user interface includes a plurality of user interface objects, the input is detected while a focus selector is over a first user interface object of the plurality of user interface objects, and the first user interface object is associated with at least the first gesture recognizer and the second gesture recognizer. Further, in some embodiments, processing the input with the first gesture recognizer includes placing the second gesture recognizer in a failed state.

Further, in the aforementioned embodiments, in response to detecting the second portion of the input on the touch-sensitive surface, the device performs (954) the first operation, including processing the input with the first gesture recognizer (e.g., the preview gesture recognizer) in accordance with the determination that the input satisfies the intensity input criteria. In some embodiments, the first intensity threshold (e.g., I_(M) in FIG. 7L) is distinct from an input detection intensity threshold (e.g., I_(L) in FIG. 7L). In some embodiments, processing of the input with the first gesture recognizer also requires a determination that the second gesture recognizer does not recognize a gesture that corresponds to the input. In some embodiments, processing of the input with the first gesture recognizer also requires a determination that the second gesture recognizer has failed to recognize a gesture that corresponds to the input (i.e., that the second gesture recognizer has transitioned to the Failed state, as discussed above with reference to FIGS. 7S and 7T).

Further, in the aforementioned embodiments, in response to detecting the second portion of the input on the touch-sensitive surface, the device performs (954) the second operation, including processing the input with the second gesture recognizer (e.g., with the pan gesture recognizer (S), FIGS. 7L-7S) in accordance with the determination that the input satisfies the pan criteria. In some embodiments, processing of the input with the second gesture recognizer also requires a determination that the first gesture recognizer has failed to recognize a gesture that corresponds to the input (e.g., the intensity of the input detected by the one or more sensors does not satisfy the first intensity threshold during the predefined time period). In the example discussed above with respect to FIG. 7Q, the preview gesture recognizer (P) has transitioned to the Failed state in accordance with a determination by the device that the intensity of the input detected by the one or more sensors does not satisfy the first intensity threshold (e.g., I_(M), FIG. 7Q) and that the input satisfies the pan criteria.

As indicated above, in some embodiments the first gesture recognizer (e.g., the preview gesture recognizer) is an intensity-based gesture recognizer and the second gesture recognizer is a pan gesture recognizer (960). In some embodiments, the second gesture recognizer (e.g., the pan gesture recognizer) recognizes a particular type or set of gestures independent of intensity of the input.

In some embodiments or circumstances, the input includes (962) a third portion of the input that is subsequent to the second portion of the input, and method 900 includes processing the third portion of the input with the first gesture recognizer. In some embodiments, in accordance with a determination that the input ceases to satisfy the first intensity threshold, the device displays the preview area at a reduced scale (e.g., reduces the size of the preview area), an example of which is shown in the transition from the user interface of FIG. 7H to the user interface of FIG. 7J (i.e., without transitioning through the user interface of FIG. 7I).

In some embodiments, the first set of gesture recognizers includes (964) a third gesture recognizer, such as a reveal gesture recognizer (e.g., gesture recognizer (R) in FIGS. 7A-7CC).

In some embodiments, in response to determining that the input satisfies (966) a second intensity threshold (e.g., a commit intensity threshold I_(H) that is higher than the first intensity threshold I_(M)), method 900 includes (e.g., subsequent to performing the first operation) processing the input with the first gesture recognizer, including replacing display of the first user interface (e.g., user interface 706, FIG. 7H) with a second user interface (e.g., user interface 710, FIG. 7I). In some embodiments in which the first operation includes displaying a preview area, performing the second operation includes ceasing to display the preview area (e.g., preview area 712, FIG. 7H). In some embodiments, the second user interface includes content that was displayed in the preview area.

In some embodiments, the first set of gesture recognizers includes (968) a fourth gesture recognizer (e.g., a commit gesture recognizer (C), as shown in FIGS. 7A-7CC), and method 900 includes, in response to determining (970) that the input satisfies a second intensity threshold (e.g., a commit intensity threshold I_(H) that is higher than the first intensity threshold I_(M)), processing the input with the fourth gesture recognizer (e.g., the commit gesture recognizer). In some embodiments, processing the input with the fourth gesture recognizer includes replacing display of the first user interface with a second user interface (and ceasing to display the preview area), for example replacing display of user interface 706, FIG. 7H, with user interface 710, FIG. 7I, and ceasing to display preview area 712, FIG. 7H.

In some embodiments, method 900 includes performing (972) a third operation in response to detecting the first portion of the input. In some embodiments, performing the third operation includes visually distinguishing (974) at least a portion of the first user interface from other portions of the first user interface. For example, the third operation may be blurring the user interface other than an object corresponding to a focus selector, by using a third gesture recognizer (e.g., a reveal gesture recognizer), as shown in FIG. 7V. In some embodiments, if the pan gesture recognizer succeeds after the third operation is performed by the third gesture recognizer, then the third gesture recognizer transitions to the Canceled state and the third operation is reversed (e.g., the blurring is reversed or undone). An example of the latter example is shown in the transition from FIG. 7P to FIG. 7Q. On the other hand, if the deep press gesture recognizer (e.g., the preview gesture recognizer) succeeds, then the third operation (the blurring) by the third gesture recognizer (e.g., a reveal gesture recognizer) is canceled, and the first operation (e.g., displaying preview area 712, as shown in FIG. 7R) is performed by the deep press gesture recognizer (e.g., the preview gesture recognizer).

In some embodiments, method 900 includes performing (976) the first operation (e.g., displaying the preview area) subsequent to performing (972) the third operation (e.g., the blurring) in accordance with the determination that the input satisfies the intensity input criteria (e.g., by reaching or exceeding I_(M)), and performing (978) the second operation (e.g., panning or scrolling at least a portion of the first user interface, FIGS. 7M-7N, FIG. 7Q, etc.) in accordance with the determination that the input satisfies the pan criteria. Typically, these determinations and operations are performed while the input remains in contact with the touch-sensitive surface. In some embodiments, while the third gesture recognizer (e.g., a reveal gesture recognizer) is processing inputs (e.g., generating touch events corresponding to the second portion of the input), the first gesture recognizer and the second gesture recognizer are evaluating the second portion of the input to determine whether the input matches gesture recognition criteria for those gesture recognizers. In such embodiments, processing the input with the third gesture recognizer does not block processing the input with the first gesture recognizer and processing the input with the second gesture recognizer.

In some embodiments, performing the second operation subsequent to performing the third operation (978) includes (980) reversing the third operation. For example, in some embodiments, an animation is displayed as the third operation is reversed (e.g., the blurring is reduced to zero over a short period of time as the user interface begins to scroll). Furthermore, in some embodiments, performing the second operation subsequent to performing the third operation includes placing the third gesture recognizer in a cancelled state.

It should be understood that the particular order in which the operations in FIGS. 9A-9D have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. For example, in some embodiments, a method performed at an electronic device with a touch-sensitive surface, a display, and one or more sensors to detect intensity of contacts with the touch-sensitive surface includes, while displaying a user interface that corresponds to at least a portion of a web page on the display, detecting a touch input on the touch-sensitive surface at a first location that corresponds to the displayed portion of the web page on the display. The method also includes, while detecting the touch input on the touch-sensitive surface, detecting an intensity of the touch input on the touch-sensitive surface (e.g., with the one or more sensors); determining whether the intensity of the touch input on the touch-sensitive surface has changed from below a first intensity threshold (e.g., a low intensity threshold, such as a mouse down intensity threshold) to above the first intensity threshold; and, in response to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the first intensity threshold to above the first intensity threshold, generating a mouse down event (and optionally, processing instructions in the web page that correspond to a mouse down event). The method further includes, subsequent to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the first intensity threshold to above the first intensity threshold, detecting the intensity of the touch input on the touch-sensitive surface; determining whether the intensity of the touch input on the touch-sensitive surface has changed from below a second intensity threshold (e.g., a high intensity threshold, such as a force down intensity threshold) that is distinct from the first intensity threshold to above the second intensity threshold; and, in response to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the second intensity threshold to above the second intensity threshold, generating a force down event that is distinct from the mouse down event. For brevity, these details are not repeated herein.

Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 1000, 1100, 1200, 1300, 1400, 1500, and 1600) are also applicable in an analogous manner to method 800 described above with respect to FIGS. 9A-9D. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 900 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 800, 1000, 1100, 1200, 1300, 1400, 1500, and 1600). For brevity, these details are not repeated here.

FIGS. 10A-10D are flow diagrams illustrating method 1000 of disambiguating a tap gesture input and a deep press input in accordance with some embodiments. Method 1000 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface (e.g., the touch-sensitive surface is a trackpad). Some operations in method 800 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 1000 provides an enhanced way to process touch inputs with instructions. Method 1000 improves efficiency in processing touch inputs.

The device displays (1002) a first user interface. While displaying the first user interface, the device detects (1004) an input on the touch-sensitive surface. Examples of the first user interface and responses to the input on the touch-sensitive surface are described above with reference to FIGS. 7A through 7K. In some embodiments, the first user interface includes a plurality of user interface objects, the input is detected while a focus selector (e.g., focus selector 705, FIG. 7A) is over a first user interface object (e.g., object 708, FIG. 7A) of the plurality of user interface objects, and the first user interface object is associated with at least a first gesture recognizer (e.g., a preview gesture recognizer) and a second gesture recognizer (e.g., a long press gesture recognizer).

In response to detecting the input (1008) while displaying the first user interface, the device performs (1010) a first operation (e.g., blurring a user interface, as shown in FIG. 7D) in accordance with a determination that the input satisfies intensity input criteria including that the input satisfies a first intensity threshold and the input remains on the touch-sensitive surface for a first predefined time period. On the other hand, in response to detecting the input (1008) while displaying the first user interface, the device performs (1012) a second operation (e.g., selecting an object, or launching an application, corresponding to a current position of the focus selector 705 and displaying the application user interface, FIG. 7B) that is distinct from the first operation in accordance with a determination that the input satisfies tap criteria, including that the input ceases to remain on the touch-sensitive surface during the first predefined time period. Stated another way, the input meets the tap criteria if the input is removed from the touch-sensitive surface prior to the end of the first predefined time period (e.g., the time period ending at time 7002, FIG. 7B). In some embodiments, the second operation is performed (1014) in accordance with the determination that the input satisfies the tap criteria, regardless of whether the input satisfies the intensity input criteria.

In some embodiments, performing the first operation includes (1020) displaying a preview area (e.g., preview area 712, FIG. 7G). Furthermore, in some embodiments, performing the second operation includes (1220) replacing display of the first user interface (e.g., user interface 706, FIG. 7A) with a third user interface (e.g., user interface 710, FIG. 7B) of a software application that corresponds to a location of the input on the touch-sensitive surface. For example, in some embodiments, a tap gesture on an object causes the display of the user interface of a software application corresponding to the object.

In some embodiments, the first intensity threshold is adjustable (1024). For example, in some such embodiments, method 1000 includes updating (1026) the first gesture recognizer to be activated in response to the intensity of the input satisfying a third intensity threshold that is distinct from the first intensity threshold. In some embodiments, the first intensity threshold is selected from a group of three or more predefined intensity thresholds (e.g., a reveal intensity threshold I_(L), a preview intensity threshold I_(M), and a commit intensity threshold I_(H)). In some embodiments, the third intensity threshold is selected from the group of three or more predefined intensity thresholds.

In some embodiments, the first intensity threshold is selected independent of any predefined intensity thresholds. In some embodiments, the first user interface is a user interface of a particular software application, and the first intensity threshold is selected or specified by the particular software application. In some embodiments, the first intensity threshold is a fixed intensity threshold that does not change while the contact is detected on the touch-sensitive surface. However, in some other embodiments, the first intensity threshold is a dynamic intensity threshold that changes over time based on predefined threshold-adjustment policies based on the activity of the user, and/or the condition of the device, and/or other environmental parameters. Adjustable intensity thresholds are discussed in more detail elsewhere in this document.

In some embodiments, method 1000 includes (1028), in response to detecting the input while displaying the first user interface, performing the second operation in accordance with a determination that the input remains on the touch-sensitive surface for the first predefined time period followed by the input subsequently ceasing to be detected on the touch-sensitive surface and the input does not satisfy the intensity input criteria. For example, For example, an input having intensity profile 7110 in FIG. 7B satisfies these criteria, and thus satisfies the tap criteria, despite the fact that the input remains on the touch-sensitive surface longer than the first predefined time period.

On the other hand, method 1000 includes (1028), in response to detecting the input while displaying the first user interface, forgoing performance of the second operation in accordance with a determination that the input remains on the touch-sensitive surface for the first predefined time period followed by the input subsequently ceasing to be detected on the touch-sensitive surface and the input satisfies the intensity input criteria. For example, an input having intensity profile 7112 or 7114 in FIG. 7K does not satisfy the tap criteria, because the input both extends past the first predefined time period and satisfies the intensity input criteria (e.g., the input has an intensity that exceeds intensity threshold I_(L) or I_(M)).

In some embodiments, detecting (1004) the input on the touch-sensitive surface includes detecting (1006, 1050) a first portion of the input and a second portion of the input that is subsequent to the first portion of the input. Furthermore, in some such embodiments, method 1000 includes, in response (1052) to detecting the first portion of the input on the touch-sensitive surface (e.g., detecting an initial contact of the input with the touch-sensitive surface), identifying a first set of gesture recognizers that correspond to at least the first portion of the input as candidate gesture recognizers, the first set of gesture recognizers including a first gesture recognizer (e.g., a preview gesture recognizer) and a second gesture recognizer (e.g., a tap gesture recognizer).

In some embodiments or circumstances, the first user interface includes a plurality of user interface objects, the input is detected while a focus selector is over a first user interface object of the plurality of user interface objects, and the first user interface object is associated with at least the first gesture recognizer and the second gesture recognizer. Further, in some embodiments, processing the input with the first gesture recognizer includes placing the second gesture recognizer in a failed state.

Further, in the aforementioned embodiments, in response to detecting the second portion of the input on the touch-sensitive surface, the device performs (1054) the first operation, including processing the input with the first gesture recognizer (e.g., the preview gesture recognizer) in accordance with the determination that the input satisfies the intensity input criteria. In some embodiments, the first intensity threshold (e.g., I_(M) in FIG. 7A) is distinct from an input detection intensity threshold (e.g., I_(L) in FIG. 7A). In some embodiments, processing of the input with the first gesture recognizer also requires a determination that the second gesture recognizer does not recognize a gesture that corresponds to the input. In some embodiments, processing of the input with the first gesture recognizer also requires a determination that the second gesture recognizer has failed to recognize a gesture that corresponds to the input (i.e., that the second gesture recognizer has transitioned to the Failed state, as shown in the transition from the user interface in FIG. 7F to the user interface in FIG. 7G).

Further, in the aforementioned embodiments, in response to detecting the second portion of the input on the touch-sensitive surface, the device performs (1054) the second operation, including processing the input with the second gesture recognizer (e.g., with the tap gesture recognizer (T), FIGS. 7A-7K) in accordance with the determination that the input satisfies the tap criteria. In some embodiments, processing of the input with the second gesture recognizer also requires a determination that the first gesture recognizer has failed to recognize a gesture that corresponds to the input (e.g., because the input has ceased to remain on the touch-sensitive surface for the first predefined time period). In the example discussed above with respect to FIG. 7B, the preview gesture recognizer (P) has transitioned to the Failed state in accordance with a determination by the device that the input has ceased to remain on the touch-sensitive surface during (i.e., for the entirety of) the first predefined time period.

As noted above, in some embodiments the first gesture recognizer (e.g., the preview gesture recognizer) is an intensity-based gesture recognizer and the second gesture recognizer is a tap gesture recognizer (1060). In some embodiments, the second gesture recognizer (e.g., the tap gesture recognizer) recognizes tap gestures independent of intensity of the input.

In some embodiments or circumstances, the input includes (1062) a third portion of the input that is subsequent to the second portion of the input, and method 1000 includes processing the third portion of the input with the first gesture recognizer. In some embodiments, in accordance with a determination that the input ceases to satisfy the first intensity threshold, the device displays the preview area at a reduced scale (e.g., reduces the size of the preview area), an example of which is shown in the transition from the user interface of FIG. 7H to the user interface of FIG. 7J (i.e., without transitioning through the user interface of FIG. 7I).

In some embodiments, the first set of gesture recognizers includes (1064) a third gesture recognizer, such as a reveal gesture recognizer (e.g., gesture recognizer (R) in FIGS. 7A-7CC).

In some embodiments, in response to determining that the input satisfies (1066) a second intensity threshold (e.g., a commit intensity threshold I_(H) that is higher than the first intensity threshold I_(M)), method 1000 includes (e.g., subsequent to performing the first operation) processing the input with the first gesture recognizer, including replacing display of the first user interface (e.g., user interface 706, FIG. 7H) with a second user interface (e.g., user interface 710, FIG. 7I). In some embodiments in which the first operation includes displaying a preview area, performing the second operation includes ceasing to display the preview area (e.g., preview area 712, FIG. 7H). In some embodiments, the second user interface includes content that was displayed in the preview area.

In some embodiments, the first set of gesture recognizers includes (1068) a fourth gesture recognizer (e.g., a commit gesture recognizer (C), as shown in FIGS. 7A-7CC), and method 1000 includes, in response to determining (1070) that the input satisfies a second intensity threshold (e.g., a commit intensity threshold I_(H) that is higher than the first intensity threshold I_(M)), processing the input with the fourth gesture recognizer (e.g., the commit gesture recognizer). In some embodiments, processing the input with the fourth gesture recognizer includes replacing display of the first user interface with a second user interface (and ceasing to display the preview area), for example replacing display of user interface 706, FIG. 7H, with user interface 710, FIG. 7I, and ceasing to display preview area 712, FIG. 7H.

In some embodiments, method 1000 includes performing (1072) a third operation in response to detecting the first portion of the input. In some embodiments, performing the third operation includes visually distinguishing (1074) at least a portion of the first user interface from other portions of the first user interface. For example, the third operation may be blurring the user interface other than an object corresponding to a focus selector, by using a third gesture recognizer (e.g., a reveal gesture recognizer), as shown in FIG. 7D. In some embodiments, if the tap gesture recognizer succeeds after the third operation is performed by the third gesture recognizer, then the third gesture recognizer transitions to the Canceled state and the third operation is reversed (e.g., the blurring is reversed or undone). On the other hand, if the deep press gesture recognizer (e.g., the preview gesture recognizer) succeeds, then the third operation (the blurring) by the third gesture recognizer (e.g., a reveal gesture recognizer) is canceled, and the first operation (e.g., displaying preview area 712, as shown in FIGS. 7E-7H) is performed by the deep press gesture recognizer (e.g., the preview gesture recognizer).

In some embodiments, method 1000 includes performing (1076) the first operation (e.g., displaying the preview area) subsequent to performing (1072) the third operation (e.g., the blurring) in accordance with the determination that the input satisfies the intensity input criteria (e.g., by reaching or exceeding I_(M)), and performing (1078) the second operation (e.g., selecting an object and displaying the user interface of an application associated with the selected object, FIG. 7I) in accordance with the determination that the input satisfies the tap criteria. In some embodiments, while the third gesture recognizer (e.g., a reveal gesture recognizer) is processing inputs (e.g., generating touch events corresponding to the second portion of the input), the first gesture recognizer and the second gesture recognizer are evaluating the second portion of the input to determine whether the input matches gesture recognition criteria for those gesture recognizers. In such embodiments, processing the input with the third gesture recognizer does not block processing the input with the first gesture recognizer and processing the input with the second gesture recognizer.

In some embodiments, performing the third operation is initiated (1080) during the first predefined time period. For example, the hint/reveal animation (e.g., progressive blurring of the first user interface in accordance with the intensity of the input on the touch-sensitive surface) is displayed even before the first predefined time period has elapsed if (i.e., in accordance with a determination that) the intensity of the input exceeds the input detection intensity threshold (e.g., I_(L), FIG. 7D) before the first predefined time period has elapsed.

It should be understood that the particular order in which the operations in FIGS. 10A-10D have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. For example, in some embodiments, a method performed at an electronic device with a touch-sensitive surface, a display, and one or more sensors to detect intensity of contacts with the touch-sensitive surface includes, while displaying a user interface that corresponds to at least a portion of a web page on the display, detecting a touch input on the touch-sensitive surface at a first location that corresponds to the displayed portion of the web page on the display. The method also includes, while detecting the touch input on the touch-sensitive surface, detecting an intensity of the touch input on the touch-sensitive surface (e.g., with the one or more sensors); determining whether the intensity of the touch input on the touch-sensitive surface has changed from below a first intensity threshold (e.g., a low intensity threshold, such as a mouse down intensity threshold) to above the first intensity threshold; and, in response to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the first intensity threshold to above the first intensity threshold, generating a mouse down event (and optionally, processing instructions in the web page that correspond to a mouse down event). The method further includes, subsequent to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the first intensity threshold to above the first intensity threshold, detecting the intensity of the touch input on the touch-sensitive surface; determining whether the intensity of the touch input on the touch-sensitive surface has changed from below a second intensity threshold (e.g., a high intensity threshold, such as a force down intensity threshold) that is distinct from the first intensity threshold to above the second intensity threshold; and, in response to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the second intensity threshold to above the second intensity threshold, generating a force down event that is distinct from the mouse down event. For brevity, these details are not repeated herein.

Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 900, 1100, 1200, 1300, 1400, 1500, and 1600) are also applicable in an analogous manner to method 800 described above with respect to FIGS. 10A-10D. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 900 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 800, 900, 1100, 1200, 1300, 1400, 1500, and 1600). For brevity, these details are not repeated here.

FIG. 11A is a high level flow diagram illustrating a method of processing touch inputs using application-independent set of predefined instructions (e.g., application-independent module 220) in accordance with some embodiments.

Application-specific module 230 displays (1102) a user interface (e.g., mail application user interface 706 in FIG. 7C).

While the user interface is displayed, application-independent module 220 detects (1104) a first portion of an input (e.g., contact 705 in FIG. 7C), and executes (1105) application-independent set of predefined instructions for providing preview operations. In some embodiments, the control of application-specific module 230 is given to application-independent module 220. By using application-independent module 220 for the preview operations, the computational burdens and the size of application-specific module 230 are reduced. The same application-independent module 220 can be used by multiple software applications for providing the preview operations, thereby reducing the memory usage. In some embodiments, application-independent module 220 is provided in an operating system or a standard library of the device, which also reduces the development time by software developers. Furthermore, application-independent module 220 provides standardized methods for interaction, which facilitate users to learn the methods quickly and reduce the cognitive burden on users.

Application-independent module 220 performs (1106) the preview operations.

In some embodiments, application-independent module 220 sends (1107) to application-specific module 230 operation information (e.g., information indicating that the preview operations have started). Application-specific module 230 receives (1108) the operation information, generates (1109) preview content, and sends (1110) the preview content to application-independent module 220. Application-independent module 220 receives (1111) the preview content.

Application-independent module 220 visually distinguishes (1112) a user interface object (e.g., mail application user interface 706 in FIG. 7D).

Application-independent module 220 receives (1113) a second portion of the input (e.g., an increased intensity of the input is detected as shown in FIG. 7E).

Application-independent module 220 displays (1114) a preview area (e.g., preview area 712 in FIG. 7G).

In some embodiments, application-independent module 220 updates (1115) the preview area (e.g., as shown in FIG. 7H, a further increase in the intensity of the input is detected and the size of preview area 712 is increased).

In some embodiments, application-independent module 220 ceases (1116) to display the preview area (e.g., as shown in FIGS. 7J-7K, preview area 712 ceases to be displayed when the intensity of the input falls below the intensity threshold I_(L)).

In some embodiments, application-independent module 220 detects (1117) a third portion of the input and display a second user interface (e.g., as shown in FIG. 7I, browser application user interface 710 is displayed in response to the intensity of the input reaching the intensity threshold I_(H)). At this time, the control of application-specific module 230 is given back to application-specific module 230, and application-specific module 230 processes (1118) subsequent inputs.

It should be understood that the particular order in which the operations in FIG. 11A have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1200, 1300, 1400, 1500, and 1600) are also applicable in an analogous manner to the method described above with respect to FIG. 11A. For brevity, these details are not repeated here.

FIGS. 11B-11C are flow diagrams illustrating method 1100 of processing touch inputs using application-independent set of predefined instructions in accordance with some embodiments. Method 1100 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 1100 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 1100 provides an enhanced way to process touch inputs with application-independent set of instructions. Method 1100 improves efficiency in processing touch inputs. By reducing the size of a software application, improving the speed of the software application, and potentially reducing the memory usage, such methods and interfaces provide a more efficient human-machine interface, thereby improving overall operational time and user experience. For battery-operated devices, such methods and interfaces conserve battery power and increase the time between battery charges. In addition, such methods reduce the burden on application developers and facilitate development of software applications that can more efficiently process touch inputs. Furthermore, such methods and user interfaces provide standardized ways in interacting with the user interfaces, thereby reducing the cognitive burden on the users and further improving the operational time and user experience.

The device displays (1130) a first user interface of a first software application (e.g., mail application user interface 706 in FIG. 7C), the first user interface including a plurality of user interface objects (e.g., user interface object 708, buttons such as “Integrate Us” and “Subtract,” an email address, and other controls), a first user interface object of the plurality of user interface objects being associated with an application-independent set of predefined instructions for preview operations (e.g., user interface object 708 is configured, for example by preregistering user interface object 708 with application-independent module 220 for the preview operations before receiving an input by a contact, to operate with the application-independent set of predefined instructions for preview operations). In some embodiments, the application-independent set of predefined instructions for preview operations is distinct from a portion of the first software application that is unique to the first software application. For example, the application-independent set of predefined instructions for preview operations is part of an application development framework that is provided to the application developer either as a drop-in module (e.g., touch processing module 220 in FIG. 1C) that is integrated with the first software application (e.g., application 1 (136-1)) and enables the first software application to interact with touch input information provided by the operating system on which the first application is running, or the application-independent set of predefined instructions for preview operations is part of the operating system that updates the first user interface for the first software application according to an API that provides consistent user interfaces for the first software application. In some embodiments, multiple different third-party applications running on the device include independent access to the application-independent set of predefined instructions. In some embodiments, multiple different third-party applications running on the device include independent instances of the application-independent set of predefined instructions. In some embodiments, multiple different applications on the device include code for interfacing with the application-independent set of predefined instructions that support with all of the third-party applications. In some embodiments, the application-independent set of predefined instructions for preview operations is separate from the first software application. In some embodiments, the application-independent set of predefined instructions for preview operations is included in the first software application.

The device detects (1132) a first portion of an input (e.g., a press input, such as input 705 in FIG. 7C) by a contact while a focus selector is over the first user interface object, in the plurality of user interface objects, on the display. In some embodiments, the input is made by a single contact on the touch-sensitive surface. In some embodiments, the input is a stationary input. In some embodiments, the contact in the input moves across the touch-sensitive surface during the input.

The device, in response to detecting the first portion of the input and in accordance with a determination that the first portion of the input satisfies reveal criteria including that the input satisfies a first intensity threshold (e.g., a “reveal” intensity threshold at which the device starts to blur the first user interface, such as I_(L) in FIG. 7C), executes (1134) the application-independent set of predefined instructions for preview operations, including providing preview content to the application-independent set of predefined instructions (e.g., operation 1110 in FIG. 11A). The preview operations performed by executing the application-independent set of predefined instructions include: visually distinguishing the first user interface object in the first user interface (e.g., blurring the first user interface other than the first user interface object as shown in FIG. 7D) (e.g., prior to displaying the preview area as shown in FIGS. 7D-7G); and, subsequent to initiation of the visual distinction of the first user interface object in the first user interface: receiving a second portion of the input that is subsequent to the first portion of the input (e.g., an increased intensity of focus selector 705 in FIG. 7G); and, in accordance with a determination that the second portion of the input satisfies preview criteria including that the input satisfies a second intensity threshold (e.g., a “preview” intensity threshold, that is higher than the first intensity threshold, at which the device starts to display a preview of another user interface that can be reached by pressing harder on the first user interface object, such as I_(M) in FIG. 7G), displaying a preview area overlaid on the first user interface (e.g., preview area 712 in FIG. 7G). The preview area includes the preview content. In some embodiments, the preview content is a reduced-size view of a user interface that is presented when the first user interface object is activated (e.g., the preview content in preview area 712 is a reduced-size view of browser application user interface 710 that is displayed in response to a tap gesture while the focus selector is on user interface object 708 as shown in FIG. 7B).

In some embodiments, subsequent to initiation of the preview operations, the preview operations are (1136) performed independent of the first software application (e.g., independent of the portion of the first software application that is unique to the first software application). For example, as shown in FIG. 11A, the preview operations, subsequent to receiving the preview content, are performed by application-independent module 220 independently of application-specific module 230.

In some embodiments, the preview operations include (1138) updating the preview area in accordance with intensity of the contact (e.g., as shown in FIG. 7H, a further increase in the intensity of the input is detected and the size of preview area 712 is increased).

In some embodiments, the preview operations include (1140), in response to detecting the second portion of the input, in accordance with a determination that the second portion of the input meets preview-area-disappearance criteria (e.g., the input ends, such as liftoff of the contact), ceasing to display the preview area and maintaining display of the first user interface (e.g., as shown in FIGS. 7J-7K, preview area 712 ceases to be displayed when the intensity of the input falls below the intensity threshold I_(L)). In some embodiments, subsequent to the device ceasing to display the preview area, the device processes a subsequent input using at least a portion of the first software application that is unique to the first software application.

In some embodiments, the preview operations include (1142): after detecting the second portion of the input, detecting a third portion of the input by the contact; and, in response to detecting the third portion of the input by the contact, in accordance with a determination that the third portion of the input satisfies user-interface-replacement criteria, replacing display of the first user interface (and an overlay of the preview area) with a second user interface that is distinct from the first user interface (e.g., as shown in FIG. 7I, browser application user interface 710 is displayed in response to the intensity of the input reaching the intensity threshold I_(H)).

In some embodiments, the preview operations include (1144): sending from the application-independent set of predefined instructions information indicating operation for the first user interface object (e.g., selection or activation of the first user interface object) (e.g., to a portion of the first software application that is unique to the first software application, such as application core 1 (230-1) in FIG. 1C) for generating a second user interface; and receiving at the application-independent set of predefined instructions the second user interface (e.g., using operations 1107 and 1111 in FIG. 11A, application-independent module 220 receives preview content, such as browser application user interface 710 in FIG. 7B, for presenting the preview content in the preview area as shown in FIG. 7G and, optionally replacing the first user interface with a second user interface that includes the preview content in response to a further increase in the intensity of the input as shown in FIG. 7I). The preview content includes at least a portion of the second user interface. In some embodiments, the preview content includes the entirety of the second user interface.

In some embodiments, the preview operations include (1146): at the first software application (e.g. a portion of the first software application that is unique to the first software application): receiving the information indicating operation for the first user interface object; generating the second user interface; and sending the second user interface to the application-independent set of predefined instructions (e.g., operations 1108, 1109, and 1110 performed by application-specific module 230 as shown in FIG. 11A). In some embodiments, other than providing the preview content, application-specific module 230 is not used for performing the preview operations.

It should be understood that the particular order in which the operations in FIGS. 11B-11C have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 900, 1000, 1150, 1200, 1300, 1400, 1500, and 1600) are also applicable in an analogous manner to method 1100 described above with respect to FIGS. 11B-11C. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 1100 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 800, 900, 1000, 1150, 1200, 1300, 1400, 1500, and 1600). For brevity, these details are not repeated here.

FIG. 11D is a flow diagram illustrating method 1150 of processing touch inputs using application-independent set of predefined instructions in accordance with some embodiments. Method 1150 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 1150 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 1150 provides an enhanced way to process touch inputs with application-independent set of instructions. Method 1150 improves efficiency in processing touch inputs. By reducing the size of a software application, improving the speed of the software application, and potentially reducing the memory usage, such methods and interfaces provide a more efficient human-machine interface, thereby improving overall operational time and user experience. For battery-operated devices, such methods and interfaces conserve battery power and increase the time between battery charges. In addition, such methods reduce the burden on application developers and facilitate development of software applications that can more efficiently process touch inputs. Furthermore, such methods and user interfaces provide standardized ways in interacting with the user interfaces, thereby reducing the cognitive burden on the users and further improving the operational time and user experience.

The device displays (1152) a first user interface of a first software application (e.g., mail application user interface 706 in FIG. 7C), the first user interface including a plurality of user interface objects (e.g., user interface object 708, buttons such as “Integrate Us” and “Subtract,” an email address, and other controls), a first user interface object of the plurality of user interface objects being associated with an application-independent set of predefined instructions for preview operations (e.g., user interface object 708 is configured to operate with the application-independent set of predefined instructions for preview operations).

The device detects (1154) a first portion of an input (e.g., a press input, such as input 705 in FIG. 7G) by a contact while a focus selector is over the first user interface object, in the plurality of user interface objects, on the display.

The device, in response to detecting the first portion of the input and in accordance with a determination that the first portion of the input meets preview criteria, executes (1156) the application-independent set of predefined instructions for preview operations (e.g., operation 1105 in FIG. 11A). The preview operations performed by executing the application-independent set of predefined instructions include: displaying a preview area overlaid on the first user interface (e.g., preview area 712 overlaid on mail application user interface 706 as shown in FIG. 7G); after detecting the first portion of the input, detecting a second portion of the input; and, in response to detecting the second portion of the input by the contact, in accordance with a determination that the second portion of the input meets user-interface-replacement criteria, replacing display of the first user interface with a second user interface that is distinct from the first user interface (e.g., in response to the intensity of contact 705 reaching the intensity threshold I_(H), mail application user interface 706, together with preview area 712, is replaced with browser application user interface 710 shown in FIG. 7I).

In some embodiments, subsequent to initiation of the preview operations, the preview operations are (1158) performed independent of the first software application (e.g., as shown in FIG. 11A, subsequent to receiving the preview content from application-specific module 230, preview operations 1106 are performed independent of application-specific module 230). In some embodiments, preview content is obtained prior to initiation of the preview operations (e.g., the preview content is obtained before operation 1112 in FIG. 11A).

In some embodiments, inputs on the touch-sensitive surface detected subsequent to replacing the display of the first user interface with the second user interface are (1160) processed with the first software application. For example, as shown in FIG. 1117, after the second user interface, such as browser application user interface 710 in FIG. 7I, is displayed, the control is given back to the first software application (e.g., browser module 147) and the first software application processes subsequent inputs on the touch-sensitive surface (e.g., by using application core 1 (230-1) alone, or optionally using application core 1 (230-1) in conjunction with touch processing module 220).

It should be understood that the particular order in which the operations in FIG. 11D have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, and 1600) are also applicable in an analogous manner to method 1150 described above with respect to FIG. 11D. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 1150 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, and 1600). For brevity, these details are not repeated here.

FIGS. 12A-12B are flow diagrams illustrating method 1200 of processing a touch input using a predefined data structure in accordance with some embodiments. Method 1200 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 1200 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 1200 provides an enhanced way to process touch inputs with a predefined data structure. Method 1200 improves efficiency in processing touch inputs. Such methods and interfaces provide a more efficient human-machine interface, thereby improving overall operational time and user experience. For battery-operated devices, such methods and interfaces conserve battery power and increase the time between battery charges.

The device displays (1202), on the display, a user interface of a software application (e.g., mail application user interface 706 in FIG. 7FF).

The device, while displaying the user interface of the software application on the display, detects (1204) an input (e.g., the input corresponding to focus selector 713 in FIG. 7FF) on the touch-sensitive surface at a location that corresponds to the user interface of the software application.

The device, in response to detecting the input, sends (1206) from an application-independent set of instructions to the software application intensity information that corresponds to the input (e.g., as shown in FIG. 7FF, application-independent module 220 sends event object 194 to application-specific module 230). The intensity information includes: a reference intensity assigned to the one or more sensors (e.g., reference intensity 7208); and a characteristic intensity that corresponds to a detected (e.g., measured) intensity of the input (e.g., characteristic intensity 7206). In some embodiments, an application-independent set of instructions is an application-independent software entity (e.g., touch processing module 220 in FIG. 1C).

In some embodiments, the characteristic intensity is (1208) further adjusted by a sensitivity value (e.g., sensitivity 7210 in FIG. 7FF). In some embodiments, the characteristic intensity includes the sensitivity value (e.g., the characteristic intensity is multiplied by the sensitivity value). For example, at 1× sensitivity, an intensity of 100 g equals a normalized intensity of 1.0, and at 2× intensity, an intensity of 50 g equals a normalized intensity of 1.0 (when the reference intensity is 100 g). In comparison, at 1× intensity, an intensity of 50 g equals a normalized intensity of 0.5.

In some embodiments, the characteristic intensity of the input is (1210) a normalized intensity value that is normalized based on the reference intensity (e.g., the normalized intensity 1.0=the characteristic intensity 100 g/the reference intensity 100 g).

In some embodiments, the intensity information includes (1212) intensity state information that is determined by one or more heuristics based on a combination of intensity-based criteria (e.g., measured contact intensity) and non-intensity-based criteria (e.g., movement of contact, duration of contact, location of contact, etc.). For example, the thresholds for determining the intensity state vary depending on movement of the contact, duration of the contact, and a location of the contact. In some embodiments, one or more of the intensity states include a dynamically determined intensity state (e.g., as described in greater detail below with reference to methods 1500 and 1600).

In some embodiments, the intensity state information is (1214) provided based on an indication from the device as to whether or not a current intensity state matches an intensity state requirement for a gesture recognizer (e.g., intensity criteria specified by a third-party application for a first gesture in a first class of gestures as described below with reference to method 1400).

In some embodiments, the intensity information includes (1216) intensity state information that has a plurality of different available state values (e.g., no-force state, hint/reveal state, peek/preview state, pop/commit state) and transitions between intensity states are used throughout the operating system to trigger operating-system driven user interactions (e.g., peek and pop, quick action menus, etc.).

In some embodiments, the characteristic intensity of the input is (1218) provided via one or more touch events that each include a characteristic intensity of a contact corresponding to the touch event (e.g., in FIG. 7II, two event objects 194 and 7194 are provided). In some embodiments, touch events are delivered to a view after a gesture recognizer associated with the view has recognized a gesture. For example, touch events that are delivered after a gesture recognizer recognizes a gesture include intensity information. In some embodiments, touch events are delivered to a view that is not associated with a gesture recognizer and the operations are performed by an application corresponding to the view based on the touch events (e.g., drawing a line with a thickness that is determined based on an intensity of one or more of the contacts in the gesture).

In some embodiments, the device displays (1220), on the display, a sensitivity control for selecting a respective intensity sensitivity setting between a plurality of intensity sensitivity settings (e.g., area 720 in FIG. 7GG or area 722 in FIG. 7HH with a plurality of intensity sensitivity settings); while displaying the sensitivity control, receives a user input corresponding to selection of the respective intensity sensitivity setting of the plurality of intensity sensitivity settings; and, in response to receiving the user input corresponding to selection of the respective intensity sensitivity setting, adjusts characteristic intensity values for a plurality of subsequent inputs by a respective sensitivity value that corresponds to the respective intensity sensitivity setting selected by the user. For example, the intensity sensitivity setting for all inputs is adjustable by the user without changing the applications that are interpreting the inputs, because the input values are adjusted before they are delivered to the applications (e.g., by same application-independent module 220).

It should be understood that the particular order in which the operations in FIGS. 12A-12B have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1300, 1400, 1500, and 1600) are also applicable in an analogous manner to method 1200 described above with respect to FIGS. 12A-12B. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 1200 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1300, 1400, 1500, and 1600). For brevity, these details are not repeated here.

FIGS. 13A-13B are flow diagrams illustrating a method of processing a touch input using a force gesture progress indicator in accordance with some embodiments. Method 1300 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 1300 are, optionally, combined and/or the order of some operations is, optionally, changed.

Method 1300 provides an enhanced way to process touch inputs with a force gesture progress indicator. Method 1300 improves efficiency in processing touch inputs. Such methods and interfaces provide a more efficient human-machine interface, thereby improving overall operational time and user experience. For battery-operated devices, such methods and interfaces conserve battery power and increase the time between battery charges.

The device displays (1302), on the display, a first user interface of a software application (e.g., mail application user interface 706 in FIG. 7A).

The device, while displaying the first user interface of the software application, detects (1304) an input on the touch-sensitive surface (e.g., focus selector 705 in FIG. 7A).

The device, while detecting the input: in response to detecting changes to intensity of the input, provides (1306) from an application-independent set of instructions to the software application a value of a first progress indicator that represents the changes to the intensity of the input (e.g., event object 194 conveyed from application-independent module 220 to application-specific module 230 as shown in FIG. 7FF); and updates the first user interface in accordance with a set of instructions in the software application that is different from the application-independent set of instructions (e.g., the first user interface is updated, for example to show the visual distinction as shown in FIG. 7D, using application-specific module 230 in FIG. 7FF) and the value of the first progress indicator (e.g., progress indicator 750 in FIG. 7D). In some embodiments, the method includes monitoring the value of the first progress indicator and updating the first user interface based on the value of the first progress indicator in response to changes to the first progress indicator. In some embodiments, the set of instructions in the software application are application-specific instructions.

In some embodiments, the value of the first progress indicator is (1308) a normalized value that indicates a status of the input between a first initial state (e.g., a hint/reveal intensity state) and a first terminal state (e.g., a peek/preview intensity state). For example, the first progress indicator has a value between 0 and 1, where 0 represents an initial state (e.g., an initial intensity, such as a beginning of the hint/reveal intensity state as shown in FIG. 7C) and 1 represents a terminal state (e.g., a terminal or target intensity, such as the peek/preview intensity state as shown in FIG. 7G).

In some embodiments, the first initial state and the first terminal state are (1310) specified by the software application (e.g., application 1 (136-1) in FIG. 1C). In some embodiments, application core 1 (230-1) of application 1 (136-1) specifies the first initial state and the first terminal state (e.g., the software application specifies whether the first terminal state is to correspond to a peek/preview intensity state or a pop/commit intensity state.

In some embodiments, progress between different states is (1312) determined by one or more heuristics based on a combination of intensity-based criteria (e.g., measured contact intensity) and non-intensity-based criteria (e.g., movement of contact, duration of contact, location of contact, etc.). In some embodiments, one or more of the intensity states is a dynamically determined intensity state (e.g., as described in greater detail below with reference to methods 1500 and 1600).

In some embodiments, the states are (1314) selected from a set of state values provided by an operating system of the device (e.g., no-force state, hint/reveal state, peek/preview state, pop/commit state) and transitions between these states are used throughout the operating system to trigger operating-system driven user interactions (e.g., peek and pop, quick action menus, etc.).

In some embodiments, the device, while detecting the input: in response to detecting changes to intensity of the input over (or to) the first terminal state: provides (1316) from the application-independent set of instructions to the software application a value of a second progress indicator (e.g., second progress indicator 752 in FIG. 7G) that represents the changes to the input. The value of the second progress indicator is a normalized value that indicates a status of the input between a second initial state and a second terminal state (e.g., between the peek/preview intensity state and the pop/commit intensity state). The device updates the first user interface in accordance with the set of instructions in the software application that is different from the application-independent set of instructions and the value of the second progress indicator. In some embodiments, the second initial state corresponds to the first terminal state. This allows the device to monitor changes to intensity of the input continuously from the first initial state to the second terminal state without a gap.

In some embodiments, updating the first user interface in accordance with the set of instructions in the software application and the value of the second progress indicator includes (1318) replacing the first user interface with a second user interface (e.g., in FIG. 7I, when second progress indicator 752 reaches the second terminal state, mail application user interface 706 is replaced with browser application user interface 710).

In some embodiments, the set of instructions in the software application is (1320) configured to provide a customized animation graphically representing changes to the intensity of the input. In some embodiments, the set of instructions in the software application is configured to provide a customized animation that graphically represents an initiation of the input. For example, the set of instructions in the software application is used to blur at least a portion of the first user interface. In some embodiments, the set of instructions in the software application is configured to provide a customized animation that graphically represents a completion of the input (e.g., the input reaching the terminal state). For example, the set of instructions in the software application is used to display a preview window. In some embodiments, the preview window in the customized animation has a non-rectangular shape (e.g., a circle). The use of the customized animation allows the device to provide an animation that is not predefined by application-independent module 220.

In some embodiments, the device, while detecting the input: in response to detecting that the input satisfies first intensity criteria (e.g., the first initial state), initiates (1322) the first progress indicator so that the value of the first progress indicator represents the changes to the intensity of the input (between the first initial state and the first terminal state). For example, in FIGS. 7B-7C, first progress indicator 750 is initiated only when the input reaches the intensity threshold I_(L). This avoids updating and tracking the first progress indicator when the first progress indicator is not needed (e.g., when the intensity of the input is below an intensity range represented by the first progress indicator).

It should be understood that the particular order in which the operations in FIGS. 13A-13B have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1200, 1400, 1500, and 1600) are also applicable in an analogous manner to method 1300 described above with respect to FIGS. 13A-13B. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 1300 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1200, 1400, 1500, and 1600). For brevity, these details are not repeated here.

FIGS. 14A-14C are flow diagrams illustrating a method of processing touch inputs based on intensity criteria specified by third-party applications in accordance with some embodiments. Method 1400 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 1400 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 1400 provides an enhanced way to process touch inputs with dynamic thresholds. Method 1400 improves efficiency in processing touch inputs. By reducing unnecessary/extraneous/repetitive inputs, such methods and interfaces provide a more efficient human-machine interface, thereby improving overall operational time and user experience. For battery-operated devices, such methods and interfaces conserve battery power and increase the time between battery charges.

The device displays (1402), on the display, a user interface of a first third-party application that runs within an operating system (e.g., mail application user interface 706 in FIG. 7JJ). Capabilities of the device are exposed to the first third-party application through an operating system framework of the operating system (e.g., a Touch Event API within UI Kit). For example, information about available gesture classes is provided to the first third-party application. The operating system framework defines a plurality of gesture classes that can be recognized by the device. A first gesture class is associated with first gesture recognition criteria for recognizing input detected on the touch-sensitive surface as a first gesture when the first gesture recognition criteria are met. The first third-party application has associated a first portion of the user interface with the first gesture from the first gesture class for a first operation (e.g., an operation performed when first pinch gesture recognizer (N₁) transitions to the Recognized state). The first third-party application has specified first intensity criteria for the first gesture associated with the first portion of the user interface for the first operation. In some embodiments, the first operation is performed when both the first gesture recognition criteria and the first intensity criteria are satisfied.

In some embodiments, the first intensity criteria include (1404) an intensity threshold (e.g., the intensity threshold I₁ in FIG. 7JJ). For example, the first intensity criteria are (at least partly) satisfied when the intensity of the input reaches the intensity threshold.

In some embodiments, the intensity threshold is selected (1406) from a set of predefined thresholds (e.g., the intensity threshold is selected from a set of predefined thresholds, such as the hint/reveal threshold, the peek/preview threshold, and the pop/commit threshold, or their corresponding intensity values, such as 100 g, 200 g, and 300 g).

In some embodiments, the intensity threshold is selected (1408) from a range of values detectable by the device (e.g., in some embodiments, the intensity threshold can be any value between 1 g and 500 g, such as 1 g, 10 g, 100 g, 450 g, etc.).

In some embodiments, the first intensity criteria include a rate of change of intensity over time, intensity of multiple contacts, a time duration of the input, a distance traveled by the input across the touch-sensitive surface, a number of contacts in the input, a direction of movement of the input, a relative timing of touchdown of contacts in the input, a motion of contacts in the input, etc. In some embodiments, the first intensity criteria includes a dynamic intensity threshold (e.g., as described in greater detail below with reference to methods 1500 and 1600).

While displaying the user interface of the first third-party application on the display, the device detects (1410) an input on the touch-sensitive surface at a location that corresponds to the first portion of the user interface of the first third-party application (e.g., a depinch gesture represented by focus selectors 715 and 717 in FIG. 7JJ).

In response to detecting the input: the device, in accordance with a determination that the input meets the first gesture recognition criteria and that the input meets the first intensity criteria specified by the first third-party application, perform (1412) the first operation associated with the first portion of the user interface of the first third-party application (e.g., in FIG. 7JJ-7KK, mail application user interface 706 is replaced with mail application user interface 724 when the depinch gesture represented by focus selectors 715 and 717 satisfies the intensity threshold I₁); and, in accordance with a determination that the input meets the first gesture recognition criteria but does not meet the first intensity criteria specified by the first third-party application, forgoes (1414) performance of the first operation associated with the first portion of the user interface of the first third-party application (e.g., in FIG. 7LL, mail application user interface 706 is not replaced with mail application user interface 724 when the depinch gesture represented by focus selectors 715 and 717 does not satisfy the intensity threshold I₁, but optionally, a zoom-in operation associated with a non-intensity based depinch gesture is performed in response to the depinch gesture represented by focus selectors 715 and 717).

In some embodiments, the first third-party application has associated (1416, FIG. 14B) the first portion of the user interface with the first gesture from the first gesture class for a second operation (e.g., a non-intensity based pinch gesture recognizer is associated with zoom-in/zoom-out operations). The first third-party application has not specified the first intensity criteria for the first gesture associated with the first portion of the user interface for the second operation. In some embodiments, the first third-party application has not specified any intensity criteria for the first gesture associated with the first portion of the user interface for the second operation. In response to detecting the input, the device, in accordance with a determination that the input meets the first gesture recognition criteria but does not meet the first intensity criteria specified by the first third-party application, performs the second operation associated with the first portion of the user interface of the first third-party application (e.g., in FIG. 7LL, when the depinch gesture represented by focus selectors 715 and 717 does not satisfy the intensity threshold I₁, mail application user interface 706 is zoomed in); and, in accordance with a determination that the input meets the first gesture recognition criteria and that the input meets the first intensity criteria specified by the first third-party application, forgoes performance of the second operation associated with the first portion of the user interface of the first third-party application (e.g., in FIG. 7KK, when the depinch gesture represented by focus selectors 715 and 717 satisfies the intensity threshold I₁, mail application user interface 724 is not zoomed in).

In some embodiments, a second gesture class is associated (1418) with second gesture recognition criteria for recognizing input detected on the touch-sensitive surface as a second gesture when the second gesture recognition criteria are met. The first third-party application has associated the first portion of the user interface with the second gesture from the second gesture class for a third operation (e.g., in FIG. 7MM, the two-finger pan gesture recognizer (2S) is associated with the first portion of mail application user interface 706). The first third-party application has specified second intensity criteria (e.g., intensity threshold I₂ in FIG. 7MM) for the second gesture associated with the first portion of the user interface for the third operation. In response to detecting the input, the device, in accordance with a determination that the input meets the second gesture recognition criteria and that the input meets the second intensity criteria specified by the first third-party application, performs the third operation associated with the first portion of the user interface of the first third-party application (e.g., displaying review window 726 showing a review of the linked website on mail application user interface 706 as shown in FIG. 7NN); and, in accordance with a determination that the input meets the second gesture recognition criteria but does not meet the second intensity criteria specified by the first third-party application, forgoes performance of the third operation associated with the first portion of the user interface of the first third-party application (e.g., when the input does not meet the intensity threshold I₂, review window 726 is not displayed).

In some embodiments, the device displays (1420, FIG. 14C), on the display, a user interface of a second third-party application that runs within the operating system and is different from the first third-party application (e.g., browser module 147 in FIG. 1A). The second third-party application has associated a second portion of the user interface of the second third-party application with the first gesture from the first gesture class for a first operation (e.g., the address window of browser application user interface 710 is associated with the third pinch gesture recognizer (N₃) for replacing browser application user interface 710 with tabs management view 728 shown in FIG. 7PP). The second third-party application has specified third intensity criteria (e.g., the intensity threshold I₃ in FIG. 7PP) for the first gesture associated with the second portion of the user interface for the first operation. The third intensity criteria are different from the first intensity criteria (and, optionally, the third intensity criteria are different from the second intensity criteria). While displaying the user interface of the second third-party application on the display, the device detects an input on the touch-sensitive surface at a location that corresponds to the second portion of the user interface of the second third-party application (e.g., a depinch gesture represented by focus selectors 723 and 725 is detected on the address window of browser application user interface 710 in FIG. 7OO). In response to detecting the input a location that corresponds to the second portion of the user interface of the second third-party application, the device, in accordance with a determination that the input at the location that corresponds to the second portion of the user interface of the second third-party application meets the first gesture recognition criteria and that the input meets the third intensity criteria specified by the second third-party application, performs the first operation associated with the second portion of the user interface of the second third-party application (e.g., browser application user interface 710 is replaced with tabs management view 728 as shown in FIG. 7PP); and, in accordance with a determination that the input at the location that corresponds to the portion of the user interface of the second third-party application meets the first gesture recognition criteria but does not meet the third intensity criteria specified by the second third-party application, forgoes performance of the first operation associated with the second portion of the user interface of the second third-party application. For example, when the intensity of the depinch gesture represented by focus selectors 723 and 725 is below the intensity threshold I₃, no action is performed as shown in FIG. 7QQ (e.g., tabs management view 728 shown in FIG. 7PP is not displayed).

It should be understood that the particular order in which the operations in FIGS. 14A-14B have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1200, 1300, 1500, and 1600) are also applicable in an analogous manner to method 1400 described above with respect to FIGS. 14A-14B. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 1400 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1200, 1300, 1500, and 1600). For brevity, these details are not repeated here.

FIGS. 15A-15B are flow diagrams illustrating a method of processing touch inputs based on dynamic thresholds in accordance with some embodiments. Method 1500 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 1500 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 1500 provides an enhanced way to process touch inputs with dynamic thresholds. Method 1500 improves efficiency in processing touch inputs. By reducing unnecessary/extraneous/repetitive inputs, such methods and interfaces provide a more efficient human-machine interface, thereby improving overall operational time and user experience. For battery-operated devices, such methods and interfaces conserve battery power and increase the time between battery charges.

The device displays (1502), on the display, a user interface (e.g., mail application user interface 706 in FIG. 7RR).

While displaying the user interface, the device detects (1504) an input on the touch-sensitive surface (e.g., the input corresponding to focus selector 727 in FIG. 7RR).

In response to detecting the input while displaying the first user interface, and while detecting the input, the device, in accordance with a determination that the input satisfies first timing criteria and first intensity input criteria, performs (1506) a first operation (e.g., visually distinguishing user interface object 708 as shown in FIG. 7SS). The first timing criteria require that the input remain on the touch-sensitive surface while a first time period elapses (e.g., through a time period p1 ending at time 7124, as shown in FIG. 7SS). The first intensity input criteria require that the input satisfy a first intensity threshold (e.g., the intensity threshold I_(L) shown in FIG. 7SS) at an end of or subsequent to the first time period (e.g., at a time subsequent to or at an end of the first time period).

In some embodiments, the first time period starts (1508) in response to detecting the input on the touch-sensitive surface (e.g., in FIG. 7SS, the time period p1 starts from the initial detection of focus selector 727).

In some embodiments, while detecting the input, the device, in accordance with a determination that intensity of the input has decreased below a reference intensity threshold, restarts (1510) the first time period (e.g., as shown in FIG. 7UU, when the intensity of the input decreases below the reference intensity threshold I_(R), the first time period restarts from time 7146 when the intensity of the input has fallen below the reference intensity threshold I_(R)). In some embodiments, the reference intensity threshold is determined based on a maximum intensity detected during a predefined detection time period and an intensity reduction margin (e.g., a fixed margin such as 10 g, 20 g, 30 g, or 40 g, or a dynamic margin such as 5%, 10%, 20%, or 30% of the maximum intensity of the contact), such as I_(margin) in FIG. 7UU. In some embodiments, reference intensity threshold is determined based on the maximum intensity detected since the time period started (e.g., since moment the input was detected or since the last time the time period restarted) and the intensity reduction margin. For example, the reference intensity threshold corresponds to the maximum detected intensity minus the intensity reduction margin (e.g., I_(margin) in FIG. 7UU). In some embodiments, the reference intensity threshold continues to be updated while the input is detected (e.g., as shown in FIG. 7VV, the reference intensity threshold is updated based on changes to the intensity of the input).

In some embodiments, while detecting the input, the device, in accordance with the determination that the intensity of the input has decreased below the reference intensity threshold, resets (1512) the reference intensity threshold (e.g., in FIG. 7VV, when the intensity of the input decreases below a first reference intensity I_(R1), the reference intensity is reset to a second reference intensity I_(R2)). In some embodiments, the reference intensity threshold is changed based on the intensity of the input detected when the reference intensity threshold is reset (e.g., the second reference intensity I_(R2) is determined based on the intensity of the input when the reference intensity threshold is reset, which is I_(R1)). For example, the reference intensity threshold is reset to the intensity of the input, detected when (or immediately before) the reference intensity threshold is reset, minus the intensity reduction margin (e.g., in FIG. 7VV, the second reference intensity I_(R2) is the first reference intensity I_(R1) minus the intensity margin I_(margin)).

In some embodiments, in response to detecting the input while displaying the first user interface, in accordance with a determination that the input does not satisfy the first timing criteria and/or the first intensity input criteria, the device forgoes (1514) the first operation (e.g., when the input follows intensity pattern 7130 or intensity pattern 7132 in FIG. 7RR, the first operation, such as visually distinguishing user interface object 708 as shown in FIG. 7SS, is not performed).

In some embodiments, in response to detecting the input while displaying the first user interface, the device, in accordance with a determination that the input satisfies second timing criteria and second intensity input criteria, performs (1516, FIG. 15B) a second operation that is distinct from the first operation (e.g., as shown in FIG. 7TT, when the input satisfies the second timing criteria based on the time period p2 ending at time 7136 and the second intensity input criteria based on the intensity threshold I_(M), preview area 712 is displayed). The second timing criteria require that the input remain on the touch-sensitive surface while a second time period elapses. In some embodiments, the second time period is identical to the first time period. In some embodiments, the second time period is distinct from the first time period. The second intensity input criteria require that the input satisfy a second intensity threshold, that is distinct from the first intensity threshold (e.g., the second intensity threshold is higher than the first intensity threshold), at an end of or subsequent to the second time period (e.g., at a time subsequent to or at an end of the second time period).

In some embodiments, the device, in response to detecting the input and in accordance with the determination that the input satisfies the first timing criteria and the first input criteria, performs (1518) the first operation including processing the input with a first gesture recognizer (e.g., the reveal gesture recognizer (R) described above with respect to FIGS. 7A-7CC); and, in response to detecting the input and in accordance with a determination that the input satisfies the second timing criteria and the second intensity input criteria, performs the second operation including processing the input with a second gesture recognizer (e.g., the preview gesture recognizer (P) described above with respect to FIGS. 7A-7CC). In some embodiments, processing the input with the second gesture recognizer includes placing the first gesture recognizer in a failed state.

In some embodiments, processing the input with the first gesture recognizer initiates placing a tap gesture recognizer in a cancelled state. In some embodiments, processing the input with a tap gesture recognizer initiates placing the first gesture recognizer in a cancelled state. In some embodiments, processing the input with a long press gesture recognizer initiates placing the first gesture recognizer in a cancelled state.

In some embodiments, the device detects (1520) an end of the input (e.g., detecting liftoff of a contact that corresponds to the input from the touch-sensitive surface); and, in response to detecting the end of the input, in accordance with a determination that the input satisfies third timing criteria distinct from the first timing criteria (and from the second timing criteria), performs a third operation that is distinct from the first operation (and from the second operation). For example, if the device detects a quick tap input (e.g., an input following input pattern 7132 in FIG. 7RR) even if that tap input satisfies the first intensity threshold, the device performs an operation that is associated with (e.g., mapped to or assigned to) the tap input (e.g., displaying browser application user interface 710 shown in FIG. 7B) rather than performing an operation that is associated with (e.g., mapped to or assigned to) the first intensity threshold.

In some embodiments, in response to detecting the end of the input, in accordance with a determination that the input does not satisfy the third timing criteria or the first timing criteria, the device forgoes (1522) performance of any operation. For example, if the device detects a long contact that is longer than the third timing criteria and satisfies the first intensity threshold but does not satisfy the first timing criteria (e.g., an input following input pattern 7131 in FIG. 7RR), the device does not perform either the operation that is associated with (e.g., mapped to or assigned to) the tap input or the operation that is associated with (e.g., mapped to or assigned to) the first intensity threshold.

It should be understood that the particular order in which the operations in FIGS. 15A-15B have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1200, 1300, 1400, and 1600) are also applicable in an analogous manner to method 1500 described above with respect to FIGS. 15A-15B. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 1500 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1200, 1300, 1400, and 1600). For brevity, these details are not repeated here.

FIGS. 16A-16B are flow diagrams illustrating method 1600 of processing touch inputs based on dynamic thresholds in accordance with some embodiments. Method 1600 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 1600 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 1600 provides an enhanced way to process touch inputs with dynamic thresholds. Method 1600 improves efficiency in processing touch inputs. By reducing unnecessary/extraneous/repetitive inputs, such methods and interfaces provide a more efficient human-machine interface, thereby improving overall operational time and user experience. For battery-operated devices, such methods and interfaces conserve battery power and increase the time between battery charges.

The device displays (1602), on the display, a user interface (e.g., mail application user interface 706 in FIG. 7WW).

While displaying the user interface, the device detects (1604) an input on the touch-sensitive surface (e.g., the input corresponding to focus selector 729 in FIG. 7WW).

In response to detecting the input while displaying the first user interface, and while detecting the input, in accordance with a determination that the input satisfies an activation intensity threshold, the device performs (1606) a first operation (e.g., when the intensity of input 7156 exceeds first intensity threshold component 7154, mail application user interface 706 is replaced with browser application user interface 710). The activation intensity threshold includes a first intensity threshold component (e.g., first intensity threshold component 7154 in FIG. 7WW) that decreases from a first intensity value (e.g., the initial intensity threshold I_(H)) over time.

In some embodiments, the activation intensity threshold includes (1608) a second intensity threshold component (e.g., second intensity threshold component 7168 in FIG. 7YY) that follows intensity of the input with a delay. In some embodiments, the second intensity threshold component is obtained by applying a low pass filter on the intensity of the input.

In some embodiments, the activation intensity threshold is (1610) a sum of the first intensity threshold component and the second intensity threshold component (e.g., in FIG. 7YY, activation intensity threshold 7170 is a sum of first intensity threshold component 7154 and second intensity threshold component 7168). In some embodiments, the activation intensity threshold is set in a way such that it is no less than a minimum activation intensity threshold (e.g., as shown in FIG. 7BBB, activation intensity threshold 7180 is no less than baseline threshold 7182).

In some embodiments, the first intensity threshold component decreases (1612) after a predefined time interval from a moment the input is detected (e.g., in FIG. 7WW, first intensity threshold component 7154 decreases after the predefined time interval p3, which begins when the input is initially detected).

In some embodiments, in accordance with a determination that the first intensity threshold component is not below a reference intensity threshold, the first intensity threshold component follows (1614) a decay curve that decreases after a predefined time interval (e.g., from a moment the input is detected as shown in FIG. 7WW or from a moment the peak operation has been performed), and, in accordance with a determination that the first intensity threshold component is below the reference intensity threshold, the first intensity threshold component follows a decay curve that decreases starting at a time determined without reference to the predefined time interval (e.g., as shown in FIG. 7XX, first intensity threshold component 7164 starts to decay when the intensity of the input falls below the reference intensity threshold I_(R)). In some embodiments, the reference intensity threshold is determined based on a maximum intensity detected during a predefined detection time period and an intensity reduction margin. In some embodiments, reference intensity threshold is determined based on the maximum intensity detected since the moment the input is detected and the intensity reduction margin. For example, the reference intensity threshold corresponds to the maximum detected intensity minus the intensity reduction margin. In some embodiments, the reference intensity threshold continues to be updated while the input is detected.

In some embodiments, in response to detecting the input while displaying the first user interface, and while detecting the input, in accordance with a determination that the input satisfies first timing criteria and first intensity input criteria, the device performs (1616, FIG. 16B) a second operation (e.g., a peek/preview operation). For example, as shown in FIG. 7ZZ, when input 7172 satisfies the first timing criteria and the first intensity input criteria at time 7124, the second operation (e.g., displaying preview area 712 as shown in FIG. 7G) is performed, before performing the first operation (e.g., replacing mail application user interface 706 with browser application user interface 710 as shown in FIGS. 7G-7I). The first timing criteria require that the input remain on the touch-sensitive surface while a first time period elapses. The first intensity input criteria require that the input satisfy a first intensity threshold at an end of or subsequent to the first time period (e.g., at a time subsequent to or at an end of the first time period).

In some embodiments, the first intensity threshold component follows (1618) a decay curve that decreases after a predefined time interval from a moment the input satisfies the first timing criteria and the first intensity input criteria. For example, as shown in FIG. 7ZZ, the decay of the first intensity threshold component in activation intensity threshold 7174 starts at time 7176, which corresponds to the predefined time interval p3 after time 7124 when the input satisfies the first timing criteria and the first intensity input criteria.

In some embodiments, the input is (1620) a continuous gesture that includes a first increase in intensity and a second increase in intensity that is subsequent to the first increase in intensity and a decrease in intensity between the first increase in intensity and the second increase in intensity (e.g., in FIG. 7AAA, input 7178 includes a first increase in intensity from below I_(L) to above I_(M), followed by a decrease in intensity from above I_(M) to below I_(L), followed by a second increase in intensity from below I_(L) to above I_(L) (and above I_(M)) without releasing input 7178), while the input remains in contact with the touch-sensitive surface between the first increase in intensity and the second increase in intensity. The device, in response to detecting the first increase in intensity of the input, performs the second operation (e.g., input 7178 satisfies the first timing criteria and the first intensity input criteria at time 7124, and initiates the second operation, such as displaying preview area 712 as shown in FIG. 7G); and, in response to detecting the second increase in intensity of the input, performs the first operation (e.g., input 7178 satisfies activation intensity threshold 7180 at time 7179, and initiates the first operation, such as replacing mail application user interface 706 with browser application user interface 710 as shown in FIGS. 7G-7I).

It should be understood that the particular order in which the operations in FIGS. 16A-16B have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1200, 1300, 1400, and 1500) are also applicable in an analogous manner to method 1600 described above with respect to FIGS. 16A-16B. For example, the touch inputs, user interface objects, intensity thresholds, and animations described above with reference to method 1600 optionally have one or more of the characteristics of the touch inputs, user interface objects, intensity thresholds, and animations described herein with reference to other methods described herein (e.g., methods 800, 900, 1000, 1100, 1150, 1200, 1300, 1400, and 1500). For brevity, these details are not repeated here.

In accordance with some embodiments, FIG. 17 shows a functional block diagram of electronic device 1700 configured in accordance with the principles of the various described embodiments. The functional blocks of device 1700 are, optionally, implemented by hardware, software, firmware, or a combination thereof to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in FIG. 17 are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

As shown in FIG. 17, electronic device 1700 includes display unit 1702 configured to display one or more user interfaces; touch-sensitive surface unit 1704 configured to receive user inputs; one or more sensor units 1706 configured to detect intensity of contacts with the touch-sensitive surface unit 1704; and processing unit 1708 coupled to display unit 1702, touch-sensitive surface unit 1704 and one or more sensor units 1706.
